Keith Frankie Nov 13, 2017 4:37 PM (in response to Prabhakar Purushothaman)Best practice would be to run the study for at least 2 or 3 times the shock duration. You can see that your max displacement is still increasing when the study ends. To do this you'll have to extend the definition of your input load.
You don't need to define a curve for your steady state loading since it doesn't vary at all.
I'd guess you're using a nonlinear/dynamic study. In this case you could run hand calcs to at least verify the resonant frequencies are correct.
You might consider a book like "Vibration Analysis with SOLIDWORKS Simulation 2018" published by SDC.

Thank you for reply kindly suggest some text books for stress and deflection hand calculations for shock loading of cantilever beams

Philip Huerta May 18, 2018 12:14 PM (in response to Prabhakar Purushothaman)Prabhakar,
I am trying to do a similar analysis, a halfsine shock pulse on a structure. However, I do not see how to see up the G's vs time halfsine shock pulse. I only see the options to set up a frequency curve and only two points. Under modal time analysis, I also only see a table with two points. Can you please show me how to set up this shock pulse analysis?
Thank you
Philip
