AutoCAD Inventor :: Measuring Forces During Simulation
Jan 7, 2013
If you can imagine a cylinder sliding on curve joint. Let’s say the curve is in the XY plane. In the output grapher it is possible to display the force as the cylinder slides around the curve. However if I understand it correctly the magnitude of the force will be in the direction perpendicular to the point of contact between the cylinder and the curve? In which case is it possible to actually find out the individual X and Y components of the force? That is to say the magnitude of the force in the X or Y plane of the curve?

IV 2011.
I have an assembly with a FEA simulation result. I can run a report and get the reaction forces and moments at each constraint. I would like to run a new simulation with different constraints and use the reaction results from the first simulation as loads in the second one.
Currently I do this by running a report on the 1st simulation to get a table of the reaction results. I then manually add those forces to the 2nd simulation. This takes time to type and the forces must be edited each time I re-run the 1st simulation.
Is there a way to use parameters to automate this?

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 using Inventor 2014 to do a simple stress analysis.
I am looking for the reaction forces at fixed boundaries, but I can't find how I can get them. Displacement, stresses, strains, everything works, but where are reaction forces?

I use the "M" measure command a lot, Is there any other good ways to dimension in assembly? I often need to know the distance between the edge of a part and another based on a fixed view, which if the two edges are straight and on the same plane works ok but I need to measure the height of two parts which are on different planes or the distance between arcs and curves as these tend to always work from the centers?
I need a command that will basically fix the plane to the current view to get the required dimensions, is there anything available?

So it isn't a major issue but I know how measure used to show a blue line when measuring between two faces or points that it measured (by default the closest distance) but ever since installing 2014 I no longer see those lines. Any setting somewhere or if that was just removed completely?

I need to assign the dimension in my screenshot to a parameter so I can use it to drive another assembly. However, I can't find any way to capture it in a usable manner.
In the screenshot I have an associative part inserted that contains only a sketch with the projected line and point that I wish to measure between, but the geometry in the sketch does not update when the model geometry changes. This seems to be normal behavior?

I'm having a real problem with a part I'm trying to develop:
I'm attempting to have a single timber part that has several draft face features within it, so I can control the bevelsa on the part with iLogic at a later date. The problem I'm having is that when the "running bevel" changes direction it throws out the bevels on the ends. (I've attached the file, it's very difficult to put into words.
But basically: When the running bevel is "forward" the end bevel measures 20degrees (as it should) When I flip the running bevel to "backwards" the same end bevel now measure 19.7degrees while the input parameter still says 20.

Two different problems (questions). These are IV2012 files but the problems are the same in 2013.
Open the two attached ipt's. Launch the Measure Distance tool and measure between the blue an red face on the DimTest. It should read 1 inch.
Change to DimTest Derive using the tabs on the status line. Measure still gives 1 in. Change precision to All Decimals. The mouse pointer changes to calipers and the distance now measure 1.004 (which is correct)
Switch back to DimTest again using the tabs.
Measure again and notice the mouse pointer still shows the calipers which imply that it is going to return all decimals but the dimension given is still just 1 inch. Either the mouse pointer should change back or all decimals should stick.
OpenDimTest.dwg. Manage> Modify> Replace Model Reference and pick DimTestDerive.
ALL dims disappear and the origin indicator goes sick.

I've created a successful FEA simulation in Inventor 2014 and obtained results. But I want to see the highest stress in a defined area that is smaller than the entire part (I have some stress concentrations that are throwing off my 'max'). Is there a way to probe an area instead of just a point? I'm tired of creating a dozen probes to find the 'local max'.

I'm developing a program which runs several simulations and obtains the results automatically.
I'm using the dynamic simulation API created in Inventor 2013. For that I use the GetResultValues(ByRef values() as Double) method of the class DSResult.
I used the method inside the VBA of inventor and worked well. But when I wrote the program in Visual Basic Express 2010, the method doesn't return anything.
I share an excerpt of the
Dim odoc As AssemblyDocument
odoc=invApp.Documents.Open(testPath, True)
Dim dsman As Inventor.SimulationManager = odoc.ComponentDefinition.SimulationManager
Dim dssim As Inventor.DynamicSimulation = dsman.DynamicSimulations.Item(1)
Dim oJoints As Inventor.DSJoints = dssim.DSJoints
oJoint = oJoints.Item(1)
[code]....
The method GetResultValues(values) should modify 'values' to a time,value vector.
It works well inside Inventor, but doesn't in the program in VB, although it runs the simulations and does everything else right.

I'm trying to run my cleanup script on a set of drawings just received from a consultant. Unfortunately every time a DWG is opened the purge fails with:
PURGE cannot be used on partially opened drawings.
Now to get the file opened NON-partially, I have to first open as partial and click the "Load All" button and "Yes" to bloodywell open it normally. Then the purge actually "works".
This needs to be done manually. Yet even after I've done this and then saved the DWG again, another normal open again gives the same error about Purge not allowed.
how to get the DWG to open non-partially when I'm running my SCR? I don't want to clean the 80+ drawings manually.

when in simulation, if you suppress a feature is it totally taken out of the simulations workings?
I.e. if I was working on a project like some weighing scales and I had a load of objects on the scales and I then suppressed some of the objects, will the scales rise up a little to counteract the reduced weight?

Is this type of gravity experiment possible with dynamic simulation?
[URL].........
I made the cone ramp and double cone but the cone either goes the wrong way or only moves a few inches in the correct direction and then gets stuck. I’m using 3D Contact Joints and Spatial Joints and Gravity Force.

i'm developing a hexapod robot and i want to simulate the motion of the robot's leg. The mechanical of robot's leg contain a servo motor that variate your angle between 0 to 330 degre. How can i delimite the angle of servo's rotation?
Other questions, is about the fixation with bolts. How can i do for the motion simulation respect the connection of the bolt? when i do a dynamical simulation the parts that contain bolts don't stay joints, i have to do a rule of fixation with constrains?

I'm designing multiple elements for a vehicle. I need to evaluate multiple dynamic results of multiple possible designs. All the design is parametric so it modifies quickly but I can't find a way to run the dynamic simulation multiple times automatically and get the results from the output grapher for each simulation.
I am trying to do it via API but can't find the class of the dynamic simulation environment in the Object Model Chart to program it via .NET.

I have a very simple part I am trying to check using FEA; however when I get into the Simulation environment and click 'New Simulation' from Ribbon nothing happens.
The part in question is just a simple cylinder (I'm verifying what would be the best meshing spec to use in a larger assembly).

I am playing with traces in dynamic simulation and in the output grapher i get values for position like:
P
P(x)
P(y)
P(z)
and in the graph i get some values of the position but i am unsure on where the datum is at this point. I would of thought that the datum would be where the trace is attached? Where the datum is based and is it possible to set a relative datum to when the trace is set?

I'm running several dynamic simulations via the API. Then I am getting the results to write in a text file. I want to know the force in a joint so I get the vector of values via
Dim oResults As DSResults
Dim oResult As DSResult
Dim value() as Double
Call oResult.GetResultValues(value())
this vector is a time, force vector but when I verify mi data against the Output Graphe all the decimal points from the force information are gone.
Example:
In Output Grapher
Time (s)Force(N)
0.0118955.66
0.0219500.88
In the vector from API
0.01
1895566
0.02
1950088
is there a way to correct this? I'm getting many force and movement info, so I don't know which ones are reliable.

I have a question regarding simulations in Autodesk Inventor.
For example I have such part:
It is a plug made out of brass. I want to test if it will be able to withstand specified pressure. So I set up where is it constrained - on thread.
And set up pressure from inside on the cap to be 16 bar (1,6 MPa). And also assign materials. And there goes simulation . Everything seems alright. I want to run little bit different analysis. When pressure would be variable.
For example I will have pressure going from 12 bar to 16 bar, and such simulation will be running for quiet long time (as an example pressure will be 12 then raises to 16 then goes to 12 again and then raises to 16 again). I want to know after what time will this plug fail and will be destroyed? I mean i want to know when METAL will get tired and will be destroyed? I was just wondering if such a simulation is possible to be made in Autodesk Inventor?

Let me preface this by saying that we work mostly in the metal fabrication industry dealing with the elastic deformation of plastic materials that are isotropic so this question is a bit above my pay grade here.
Is it possible to simulate the stresses in a piece of glass in a simple beam scenario in Inventor (1/2" x 48" x 130" Tempered Glass)? I have a client that wants me to design a conference room table for him but I am highly uneducated about glass.
Is it possible to simulate? If not, is it possible to "fake" it and get semi-reliable results? We're at the conceptual stage here and we're curious which of our designs have a greater possibility of surviving the design validation process (which will include a glass expert at some point).

Every now and then, but recently more then I want, I get a blue screen while doing a stress analysis.
I have a pretty simple assembly with just 2 parts in it. One of these parts is built as a multibody part. It can be that the blue screens started to occur after I made a multibody design, however I am not sure about that. I downloaded and installed Inventor R13.

is 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.

why there is huge difference in Dynamic Simulation results when you use two different input methods? I used input grapher and in linear ramp, I entered input (time/ distance) manually for 6 points and ran simulation. Then I used Spline and used a text file to enter SAME data and it gave me at least 10 times different results. Can't figure out why this difference. This changes my entire design.
