Vibration Analysis in PTC Simulate 3.0

[econnolly]

I was wondering if anyone had any pointers on how to begin a simple vibration analysis in PTC Simulate 3.0.

What I've done so far:

Modelled: A plate, attached to a mass using 4 bolts (in red) as shown in the simple diagram below.

Applied Loads: Applied 1g (where g is gravity) loads in X, Y, and Z directions

Preformed a Modal Analysis

What I would like to do:

I would now like to apply vibration loads in X, Y and Z directions to the model. I would then like to view the stresses and deformation in the plate as a result of these vibrations. How do I do this.

Baby steps would be much appreciated.

1. Define a new dynamic random study
2. Enter your PSD (base excitation and then click F(x)
3. Enter your Damping Coefficient
4. Run the study

Note: The default frequency intervals will need to be adjusted after you review the response. Enter in user defined steps once you see the response to make sure you are capturing all of the energy.

First and foremost, what type of vibration load do you want to apply? Creo can do time domain, frequency domain, PSD, and response spectrum.
