Is this type of gravity experiment possible with dynamic simulation?

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.

Im trying to figure out if Inventor's dynamic simulation can simulate gravity on rope or cable shaped solids.
I have a power cord design that I want to display with its cords in various natural positions (IE Flat on a table, hanging from a wall, etc). (see image attached)
My questions are as follows:
1. Can dynamic simulation simulate a rope/cable type object falling with gravity to a natural hanging position?
2. If it can, can I also then save the resulting new shape/model and export it to showcase for rendering (or render within Inventor)?
3. I am currently creating the cords using the sweep command. Using this seems like it may cause problems for the simulation. If I use the wiring harness design part of inventor to create the power cables can it then simulate the cables naturally falling and resting due to the forces of gravity? I know the wiring harness design area is built in, but I have never even opened it before..

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 can obtain the Center of Gravity of a sub-assembly. What are the values with respect to? The origin/root of the whole assembly or the origin of the sub-assembly? How can I obtain the coordinate of the COG of a sub-assembly with respect to its origin or with respect to the whole assembly's origin?

View 3 Replies View RelatedI have a LOD in my assembly to suppress some of the components. In the assembly, it looks like the center of gravity is correct for the LOD. Now I place this assembly in an idw with the LOD active. Now I right-click on the assembly in the idw and choose "Center of Gravity". The center of gravity shown here does not represent the center of gravity for this LOD. The CG shown represents the CG of the master LOD.
Is it possible to get the center of gravity to show on the idw that represent the CG of an LOD?
Structural shape authoring has a parameter mapping for the center of gravity. What values should these be for a C channel where the part origin is at the geometric center and the center of gravity is located along the negative X axis? I checked one of the channels in content center - it had the origin located at the center of gravity and the parameter mapping was the distance to the outer web surface (positive), with the web located in the negative X direction.

For some reason it will not let me constrain a part to the center of gravity plains. I would like to constrain lifting lugs to the center of gravity so the model will automatically update itself. Is there anyway to make this work (using ilogic or anything)?
Why would Inventor tease me with showing me the center of gravity plains in an assembly but making them completely useless?
I have created assembly (lets call it main assembly) in which there are 4 other assemblies (lets call them sub assemblies).
Now in the main assembly document i want to display center of gravity of each of the sub assembly.
When i open each of the sub assemblies and turn on center of gravity of each of them, when returning to main assembly view it displays center of gravity of main assembly, not of each of the sub assemblies.
Im asking for this because i want to create a drawing of main assembly and add dimensions of each of the sub assembly centers of gravity and unfortunatly just as in assembly view, when i want to display center of gravity i can do it only for the main assembly not for each of sub assemblies.
I am currently trying to show a comparison of Center of Gravity between two assembly's. One is the original state and the other has counter weight bars. I know how to get the COG to show on my drawings, but both COG locations are the same in my drawings (but different in my assembly) My problem is when I create View Representations and I toggle the Counter Weight bars off, the COG in my drawing still remains in the same location as if they were still on. I know the hard way of accomplishing my task would be to save 2 seperate models (one with Counter Weights and one without). But I would like to take full advantage of the Representation Option.

I know that the load would be floating in the air at the center of gravity, could this be the issue?
View 5 Replies View RelatedI am trying to pinpoint the center of gravity on a curved face of an assembly. I can use the c og G command to get the true center of gravity but i would like to incorporate lifting eyes into the finished assembly. Basically I need to know how to find the C of G on a given surface. I have attached the assembly I am working on and added lifting eyes roughly where I would like them. I have tried measuring from the C of G to a face and then creating the lug above the C of G but somehow it doesn't line up.
View 7 Replies View RelatedOk received parts from a customer. It was ALL mesh features.I converted some of them(the mesh features) to Solids. Some would not convert to solids (converted to surfaces).
I need to have the COG show up correctly. Yes, I have a physical COG. I know where it is supposed to be.
I am trying to use this and several other parts (with mixed, Solids, Surfaces, Mesh features), in an assembly AND balance it all thru a common lift point.
How can I correct the COG of the individual parts, so that the assembly is correct.
I have work planes for the corrected COGs, but I am afraid that I will need to calculate the new COG for the assebmly.
I wonder how to convert the centre of gravity of a part into a work point.

I'm trying to build a VBA code in inventor 2010 to export the Center of gravity coordinates (X,Y,Z) from an inventor assembly to an excel sheet.
But I'm not able to get the iproperties for the COG from my assembly.
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'.

View 9 Replies View RelatedI'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.

View 1 Replies View Relatedwhen 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?
I am trying to discover the dynamic simulation, so I need to know is that possible to create a new Load(Torque, Force) using API?

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 installed inventor 2011 on my laptop, but the dynamic simulation menu does not appear even though I 've been many times to install it.
View 9 Replies View RelatedI 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.
