AutoCAD Inventor :: Stress Analysis Highest Local Stress?
Dec 27, 2013I've been doing a lot of work with the Stress Analysis recently, and I have wondered if a certain feature exits. When I am interpreting the results of a simulation, I'll use the probe to find out the stress in certain areas. The problem is that I can't be certain that I've picked the point of highest stress in a certain area. I know that I can find the highest overall stress, but it's hit or miss finding the 'highest local stress' as I've come to call it. I need to be able to prove that a certain member's stress is below the allowable stress, and I can't be certain of the member's highest stress unless y'all know of some way.
I am running Autodesk Inventor Professional 2014, 64-bit.
AutoCAD Inventor :: Import And Use Drawing Standards?
Sep 27, 2012I'm working on homogonizing all of our various templates, making all the new features from newer templates available in the older templates but I'm getting high centered on a step.
I've exported all of the different drawing standards and imported them all into each template which makes all of the upgraded dim styles available in all of the templates. The issue arrises when I save and close then reopen the template the imported standards are missing. It appears that under Manage, Styles Editor, if the standard is not in use it is not saved with the template. If this is the case how do I put them all "in use"? Even if I activate one of the imported standards, save, close, reopen, then activate a different standard and repeat, the imported standard is deleted.
AutoCAD Inventor :: Setting Standards In Styles Library
Jun 13, 2012We have three divisions in my company. Each division uses a different set of drawing templates.
With all of that said, in my division we are trying to setup a certain said standard that was copied from the out of the box standard ANSI one as a starting point. We were hoping to have this standard reside only in our drawing templates, but the way the styles is handling it, it would appear that this standard has to be updated/added to the global styles library.
Is this a true statement that this has to be a global styles update or is there a way to have a said standard be the default setting within just certain drawing templates without being seen or affecting other drawing templates?
AutoCAD Inventor :: Bolted Connection Generator Calculations
May 17, 2012I am using the calculation tab in the bolted connection generator. Is the maximal tangent force (Ft) the total force of plates in shear or per fastener? It appears to be the total force because changing the number of bolts changes the results.
I have been running different configurations due to a failure in a test cell and the numbers don’t seem correct. The calculation indicates that the fastener would fail at a much lower force than it actually is.
AutoCAD Inventor :: Create New Dimensioning Styles For Company To Use As Standards
Jan 25, 2012I'm using Inventor 2010.
I've been told to create new dimensioning styles for the company to use as standards when making a drawing. One thing mentioned in particular was the inclusion of 0 inches in architectural drawings.
For example: say a part is 14 feet, 1/2 inches long. Inventor shows this: 14' - 1/2" , but they want this: 14' - 0 1/2" . They've had a problem before with the 1/2 being printed strangely, and the machinist thought it said 1 1/2.
They say that including the 0 is standard, and I need to make it happen.?
AutoCAD Inventor :: General Opinion On Calculations Of Part Features
Aug 15, 2012Using inventor to calculate specific distances or counts of features on a part. Say for instance, the lineal feet of a radial edge, or the number of cutouts a part may have. If so, how are you approching this? Can be programs written with the API/iLogic or just general setup I am pretty versitle and open to any discussion.

Aug 27, 2009I am looking at the Content Center data. In this specific case, ANSI AISC Rectangular flat bar steel.
The calculations for Section Modulus seem to be the same for both parameters Wx and Wy.
The calculation for Wx shows in the column properties as: (({G_W} * {G_H} * {G_W}) / 6)
The calculation for Wy shows in the column properties as: (({G_W} * {G_W} * {G_H}) / 6)
These calculations show in the Expression Column as red text. I can modify them but I have no option to OK the dialog box.
The Moment of inertia calculations that are later in the family table use these sections as part of their calculations.
Am I wrong here in my belief that the Section Modulus calculations are wrong and therefore the Moment of Inertia are wrong also?
As an extension of this question, does the Stress Analysis in 2010 use these calculations? Are these numbers used anywhere?
AutoCAD Inventor :: Control Frame Edit Unit Attributes Use Standards Notation
Apr 3, 2012Autodesk Inventor 2010 - How do I set default for "use standards notation" to off or unchecked in the "Edit Unit Attributes" dialog box for feature control frames? I want to do this because the Feature Control Frame style unit setting does not override it as I believe it should. This causes an extra value within the tolerance box of the feature control frame if the Standard General units differ from the style’s primary units.

AutoCAD Inventor :: Trigger ILogic Rules Using API?
Mar 29, 2011I am currently using a vb.net application to control inventor using the API code.The API code is used to delete/suppress unwanted occurances from parts and sub-assemblies, depending on what is selected in the external application. It then puts all the parts and sub-assemblies together into a final assembly.
Most of the parts contain iLogic rules, to control dimensions, and these have been set to trigger when the part file is opened.I have noticed that in my final assemblies some of the parts don't appear as they should, however if i close the final assembly and open the individual part it appears to be correct. If i then open the final assembly it looks fine.
I think this might be due to the iLogic rule being triggered when the part is opened.Is there any way to trigger the rules using the API code while the final assembly is open, instead of closing it down and opening all the component parts and sub-assemblies?Or should we set the rules to trigger on a parameter change?

May 3, 2012I have an assembly with multible parts which all have iLogic rules in them. I want to controle when the rules are executed in each part, thus I have set them as "Don't run automatically". These rules are iTriggered by the top assembly, if they are active.
Is there a possibility of how I can run multiple rules simultaneously?
The code below is an example of the controle rule that determines the rules to be run but it takes one rule at the time...
IfComponent.IsActive("5580 Heating element package 1")=TrueThen
iLogicVb.RunRule("5580 Heating element basket 1", "iTriggerRule")
EndIf
IfComponent.IsActive("5580 Heating element package 2")=TrueThen
iLogicVb.RunRule("5580 Heating element basket 2", "iTriggerRule")
EndIf
.

.
up to x
I have also tried with For - Next statements...But the rules are run in the order that tey are written...
As the computer has a lot of memory in reserve; I want somehow all the iTriggerRules to be run at the same time as this would save a lot of time.
AutoCAD Inventor :: ILOGIC Workflow / Way To Add Rules
Oct 1, 2012I made a simple rule that triggers before save to ask user to make a selection, which then updates an iProperty.I created A multi value fxParameter and used the InputListbox function.
Ultimately I want to know the best way ok making this rule available to all parts, old and new.I am thinking, it will be easy enough to update my templates and embed this code into the part, as well as content center files by updating each file / template .
But for existing parts, is there a way to add these rules without the user having to do much steps.because there is an fxParameter I am thinking the user will have to know how add this to their part.I can change it to just an input box where they can type in the correct value, if that would be easier.
AutoCAD Inventor :: ILogic Rules Not Triggering
Sep 8, 2011I have been having trouble with parts that do not trigger iLogic rules. I've set the triggering events to After Open Document, but nothing triggers. I must manually open the parts and then click the iTrigger to get the rules to run. This is not all parts only a select few and seemingly random.
Is there something I can do to ensure the triggers fire and the rules to run?
Sidebar: If a part is set for trigger After Open Document should that part trigger the rules when the assembly that the part is in is opened?
AutoCAD Inventor :: ILogic Rules In Assembly
Oct 3, 2011I am very new to this whole concept of having ilogic based rules to drive your part design. I have even gotten as far as creating a ipart and having ilogic rules be able to suppress, unsuppress, change values and dimensions using ilogic rules. I now want to be able to use ilogic rules to drive some of the various(yet similiar) assemblies that I create all the time.
For instance, If I have just a flat plate as the base component with a shaft welded to it that varies in length for my assemblies. Since the shaft varies in length, I went ahead and created iparts for all the lengths of the shafts. I can manually change which shaft I want represented in the assembly, but I would like to to know how do I get Ilogic to place the different shafts based on user parameters???
I've looked into component place iparts, but can't seem to get the code to work. The list of iparts tree within the model doesn't pop up in the model tab in the ilogic rule, only the base component.

View 6 Replies View RelatedAutoCAD Inventor :: Stress Analysis Contacts
Oct 8, 2013I am trying to simulate the following:
I have an 8" OD/5.523" ID steel tube. A 5.5" OD/4.957"ID tube is placed inside. The 8" and 5.5" tubes are placed over a 4.9375"OD shaft. So basically you have a hollow shaft attached to a drive shaft, with a filler tube placed between them to fill the gap. Two 1-1/2" UNC bolts are placed in matching1.531" diameter holes in every component (thru bolted) with a nut. Tightening the nut will tend to flatten the pipes, taking up the clearance between then and creating a contact pressure on the drive shaft. I have having trouble getting all of the contacts correct since the components are not in contact at the beginning of the simulation due to the radial clearances.
Two axial bolt loads of 129,000 lbs will be placed on the tubes. I have used a sliding/no separation contact between the bolt and nut. Then I put a fixed constraint on the bottom face of the nut (not in contact with the tube) and put a 129,000 force on the top of each bolt head to simulate the axial load created by the bolt preload. What type of contact should I use between the tubes that have radial clearance?
I have attached the tubes and drive shaft. The 1-1/2" bolts and nuts (both heavy hex) were found in the library.

AutoCAD Inventor :: G-Forces In Stress Analysis
Jan 6, 2014I am trying to properly stress test a steel aircraft fuselage. I can easily model the estimated weight of the pilot, copilot, etc as loads on the airframe. However, when it comes to simulating a high-G situation, (a load factor of around 7.5 times the force of gravity), I am not sure what to do. On one hand, I can simply multiply the loads on the airframe by the load factor and see if the frame can take it. In most cases, it performs very poorly, (safety factor less than 1). However, if I model all the loads under normal conditions, (normal pilot weight, etc.), then add a gravity load equal to 7.5 G, the airframe performs well. Yet I am not sure if the loads on the airframe, (such as pilot weight), are being adjusted along with the increased gravitational load.
My question is, what is the best way to accurately simulate real world loading for high-G situations?
AutoCAD Inventor :: Stress Analysis / How To Constrain
Dec 31, 2012I am trying to determine how to properley constrain the assembly below, so that the compression of the rubber gasket will be properly indicated.
Currently I am seeing the deflection of the shelf in the downward direction, but I do not see any indication of stress in the gasket behind.Currently the gasket is "bonded" to the steel tube the screws are bonded to the shelf bracket and the steel tube.
I put in "work axis" at the center line of the shelf bracket and the CL of the gasket, but I can't find a way to constrain to a work axis.The file is too large to upload here...

AutoCAD Inventor :: Stress Analysis Disabled
Nov 13, 2013I have used a few times 'Stress analysis' before. Today I discovered it is disabled. I applied a software update (SP1, build 222), after which I could run a Stress analysis again. However, Inventor crashed soon, and after restarting it, Stress analysis is disabled again. In 'Add-In Manager' the 'Simulation: Stress analysis' is shown as 'Automatic/Loaded'.
UPDATE: I have unchecked the 'Load Automatically' option for this module, quit Inventor, started it again, loaded the module and now it seems to work. I don't know yet for how long...
UPDATE2: well I could start a Stress analysis, but everything is disabled there, I can not create a simulation for example.

not with a tight fit so it shrinks on it but it works wit a small cut in the shaft where its bolted with just a tiny metal plate.
at this place will be a stress concentration and i wanne see how the noth effect is when their is a dynamic load on it cause if i put a static load on it i know the shaft can handel it but i real life it has broken couple of times so this is what i want to investigate.
AutoCAD Inventor :: Stress Analysis Deflection
Sep 19, 2013I work for a tank building company and we are starting to use Inventor for stress analysis. We have a tank that we are designing that has a tank inside of another tank. The internal tank will be holding product while the outside tank is there to prevent product leakage in the event that the internal tank has a leak. There is piping that is welded to both the inside tank and the outside tank.
So here's my question: We know the radial deflection of the piping on the internal tank due to pressure, but we want to know what the stress is going to be on the external tank shell. Is there a way that I can input the amount of deflection and so that inventor will calculate the stresses involved?
AutoCAD Inventor :: Stress Analysis On Chassis

The problem is that the analysis that I did doesn't seem to make any sense at all, like there was no stress between the joints, the frame bent when the applied force was only 5 kg...
The metal used is mild, steel.

AutoCAD Inventor :: ILogic Rules - How To Replace All Components
Mar 1, 2012Can I use an iLogic Rule at the top assembly level to "replace all" of a particular component is that component resides in more than one subassembly? I need a rule to run and globally replace the component in all subassemblies without opening up each subassembly manually. I can run a rule in the individual subassembly that looks like the following:
If GoExcel.CellValue("3rd Party:Embedding 1", "Sheet1", "A2")=800 Then
Component.Replace("Part1:1", "OtherPartfilename.ipt", True)
End If
Is there a way to run a "replace all" command from a top level assembly?
