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 16-2(,0 Hz are 'termed "structure shake", and produce distrubances seen and felt by the vehicle occupant. The knowledge of an objectionable

'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 illust-: • rate the suitability of the measuring technique and the instrumentation • system used.
