Abstract

In this paper the laser-Doppler-velocimeter is used to measure the responsive velocity of car body and cylinder of engine. It is made of the cylindrical beam as emissive light, avalan-che pipe as receiver and wide-band monitor as signal processor. The frequency response function can be easily obtained from the output signal of laser-Doppler- velocimeter after A/D converting and FFT transforming. The modal parameters data of modal shape may be gotten with test modal software.
