A new approach for the specification and performance of shock tests is described in this paper. Many field shock sources are nonstationary random processes. When a mechanical system will be subjected, in field use, to a shock drawn from a nonstationary random process source, it is best to test the system in the laboratory using a test shock drawn from the same random process source. It is shown in this paper that when a nonstationary random process is specified, realizations of the random process can be digitally generated and then reproduced on an electrodynamic shaker. Examples are presented.
