The study of the vibration characteristics in machines has taken a front seat in engineering effort. This is particularly true in the automotive industry, where marketing a vibrating vehicle is unacceptable. Today's automobiles are a complex spring-mass-damper system which is excited into various modes of vibration. The vibrational modes falling in 10-200 Hz are termed "structure shake", and produce distrubances seen and felt by the vehicle occupant. The knowledge of an objectionable vibration in development programs. Therefore, the aim of this work is to introduce a method by which the vehicle vibration performance can be investigated in the laboratory. A chassis dynamometer was used to simulate the road-going conditions. The measurement and analysis techniques are presented herein. Samples from the results obtained for van and small saloon vehicles are included to illustrate the suitability of the measuring technique and the instrumentation system used.
