so I want to simulate the stress on a payload that is on a rocket. the payload will be exposed to 20g!
My question is do I just put a force on the payload straight downward or can the gravity option somehow be used to get an accurate result?
I'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.
I made a custom model rocket a few days ago and I posted some pics online. A lot of the rocketry community gave me crap that my fins are too small, and my nose cone was not the right shape.
I made a CAD of the rocket in inventor and I would like to run a simulation so I can see what it will look like when the air is flowing over my rocket.
Here's a STEP file of the rocket, as of now I don't have the density of the parts set because I am still trying to figure out how to add custom densities. I know that there are somethings about the rocket that don't seem right, like the nose cone that doesn't go over the sides of the tube - but that was a machining error on the actual rocket and I wanted to make the CAD as similar as possible.

Take an inducer wheel for a turbocharger. It is a complicated component and very difficult to calculate by hand. it is spinning with high revs, and the rev limit it set by the centrifugal forces acting.
Is is possible to simulate a part with a crack in inventor 2013? A customer had a part made and noticed there was a crack. We were asked to run an analysis on the crack to determine how much of a factor this crack has on the part. Is it simply just a matter of sketching the shape of the crack and removal of material or ??? The part is cylindrical in shape and the crack goes approximately 1/8 around the diameter of the part.

View 1 Replies View RelatedI'm trying to simulate a sprag clutch using Autodesk Inventor Professional 2011 (student edition) but I'm having some trouble keeping two parts from rotating together.
The flange of the driving gear sits inside the clutch hub but the two should be free to rotate relative to each other. However, when I simulate the rotation of the gear, the clutch rotates with it as well. I can sort of simulate the desired behavior by adding a torque to the clutch but I don't think this should be necessary.
I can't attach the files because they're too large but I'm hosting them here: [URL]...... and here: [URL]........... The A4_Complete is the whole clutch, but for a simpler view A3 shows the issue I'm having.
Essentially Pink gear drives the Green gear, and the Orange clutch should slip on the grey flange of the green gear but it does not.

View 9 Replies View RelatedI 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.
How to set up a symmetric stress analysis?
I read about using symmetric analysis on a symmetric assembly, but no description of how it is done.
I 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?
I 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...

and it says I don't have enough memory! How can this be? Its not that complicated of an assembly. I have done bigger. I excluded all the part I'm not using and they are all basic plate and tube parts. There are less than 20 parts in the assembly.
I 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.
I have just installed Inventor 2012 on a clients machine and the stress analysis tab is missing.
View 2 Replies View Relatedis their a possibility to applay stress like dynamic i have a shaft that has a pully on it , its conectet on an old way
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.
I 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?
I'm a student working on a team project to build a vehicle and we're required to do a stress analysis to make sure if the vehicle (chassis, supports, etc) can withstand the weight of the driver, etc.
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.
how to create a simulation of a part in a sub-assembly of the assembled design?
I manage to move only the parts in the assembly. However, I can't move the parts in a sub-assembly of the assembled design.
I am using Inventor 2009 professional and I have to run a stress analysis on a beam. I put the constraints and the forces I need and when I hit the calculate button, the results so up, but when I click on the results, nothing appears. I need to run this calculation and do not want to resort to hand calculations.

View 2 Replies View RelatedI'm performing a static stress analysis on a benchframe. The benchframe is imported out of a STP file and I assume that's where the problems begin.
When I start the simulation, everything goes well. When I see the results, almost the whole part is blue, and only a really small part in a corner is shown red, with extremely high stresses.
The corner is actually not what I wanted to test, but it is messing up the other visible results because now I have to place probes all over the part to see the stresses (because the colors are calibrated with the high peak).
I have tried working with local mesh control and convergences, but I can't control the results in the small corner. I also tried rebuilding surfaces and adding fillets.
Is it possible to set a maximum stress, so that the other colors are visible in the important areas. It is not possible to exclude the corner from the simulation because it's part of a substantial part.

How to make stress analysis from wood?
Does not allow to choose a wood? I have problem with material.
I am having problems with 2013 and trying to access the Stress analysis, when going into environments the tab is consistently greyed out. I made a very simple model and pasted the snips below.
-Environments Tab
-Add In manager.
I currently use Factory Design Suite Premium 2012/Inventor 2012 (64-bit, Factory Premium) but notice there is no stress analysis option in the environments tab...shouldn't it be there or is an additional purchase required?
