Hello to the simulia community,
Here's the problem:
I want to carry out a test under sine sweep loading. To do this, I first run a frequency step to enable SIMULIA to calculate the natural frequencies. In this first frequency step, I impose my boundary conditions. In the next Harmonic Response step, I define a basic motion which is automatically assigned to the boundary conditions defined in the previous frequency step. In this way, I can assign an amplitude to the basic motion to describe the dependence of the acceleration signal.
In my case, this is a constant amplitude between 10 and 1000Hz.
But when I plot the acceleration output at the center of my tool /frequency, the result is not physical.
I should find an output level equal to the input before my amplification.
What have I done wrong or misunderstood?
Thank you very much.
Lambert
