Hi all,
in the dynamic analysis we have (Creo 2):
- time analysis
- shock analysis
- frequencies analysis
- random analysis
I need always a modal analysis before; but I have the problem that I can't use contact surfaces. So I can analyze only parts or "solid assemblies".
Or not?
In shock analysis you apply the load only at the constraints and you can insert the data as dependent by time.
In random, frequencies and time analysis you can insert the load from the base OR from the "typical load".
But even in non-linear static analysis you have the possibility to impose the dependency by the time.
1. What is the real difference?
Can I have more details about dynamic analysis? (PTC pdf)
I need studying the contact pressures between a shaft and a cam keyed on it and moved by a key.
The axial movement is prevented by a collar closed by a screw.
I have more forces on the system that vary on a cycle of 0.428 ms (in primarily the force of the cam)
I need a non-linear analysis (there are contact regions) and to vary the forces in the time.
2. How can I do?
