Thanks Peteroznewman,

the time history force time history are simulation results extracted form a software called trucksim where an event  of a semi trailer vehicle traversing a bumpy road has been simulated, this was done because an experimental test procedure could not be done to get the required data

Can you please explain to me how to convert a force time history  data can be converted into a psd vs frquency.

Thank you
