Dynamic Simulation Question.

[Anonymous]

The attached image shows that I have been able to export some loads for FEA analysis. They are shown as the last items in the list. However, when doing an FEA on the part, I can not find the method to import these loads. The instructions are to import the Motion Loads. Where is the button?
Thanks Bill S

I found it. Has anyone ever analized a crankshaft? Where the loads are pressures on the pistons.
Thanks

Hi Bill
with Dynamic Simulation, you can simulate pressure as a function of Force (using the surface area of the top of piston).
You can use the Input Grapher to define the Magnitude of the Force. In this tools, the Spline law allows to read your force's data due to the combustion. You can also change the reference to have the rotation of the crankshaft and use the Modulo (or Cyclical) property to reproduce the force every 2 rotations of the crankshaft.
I attach 2 images to illustrate the Input Grapher (values are given for example).
Hope it helps you
