摘要

A modal survey test of the Combined Release and Radiation Effects Satellite (CRRES) was conducted using single point random excitation in each of three orthogonal axis. The absence of a significant predicted mode lead to an additional test using multi-point random polyreference techniques. All modes found by both techniques were analyzed. The setup, instrumentation and analysis techniques for both methods are described. The results and the economical aspects of the two techniques are compared.
