1. A method of designing a test fixture configured to mount to a vibration slip table and fix a test article to the vibration slip table during a vibration test, the method comprising:
performing finite element analysis via a topology optimizing module of a computer system using one or more boundary conditions determined from parameters of the vibration slip table, the test article, or the vibration test to optimize a topology of the test fixture; and
outputting from the topology optimizing module a geometric model of the test fixture having the optimized topology;
wherein a motive source vibrates the vibration slip table during the vibration test;
wherein the one or more boundary conditions include a g-load parameter; and
wherein the g-load parameter is converted from a selected power spectral density curve according to which the motive source is powered to vibrate the vibration slip table during the vibration test.
