How to Simulate a Bump Test?

I am trying to simulate a bump test on an electronic enclosure. I have been given the shape of the pulse (half sine), the peak acceleration and the pulse duration. So I think the most likely study will be a linear dynamic modal time history analysis. I have also been given the number of bumps (around 4000) and that the repetition rate will be 1 to 3 bumps per second. My question is how do I incorporate the number of bumps and the repetition rate in the study?


The only thing I can think of is to plot a very long graph on excel showing each pulse and copy and paste it into the uniform base excitation curve and then run the study. But that would take a lot of computing time and space. Is there a better way to do it?
