摘要

An efficient, direct measurement, mode survey test procedure is presented. The procedure derives from the recognition that single-shaker frequency response functions of a linear, elastic structures can be scaled and summed to yield frequency response functions corresponding to multiple-shaker excitation. Thus, the operations to establish the multiple force levels needed to isolate modes for measurement can be performed numerically on a small laboratory computer/data acquisition system. In addition, this also introduces the possibility of numerically identifying mode parameters from single-shaker frequency response functions by using traditional sine-dwell testing techniques.
