ANALYSIS TECHNIQUE FOR VEHICLE SHAKE
The vibrations of a vehicle occurring at road wheel rotation frequency are always a major problem for the tyre engineer. Methods of detecting the various sources of shake are made difficult by the beating between them. This paper gives details of a technique developed to obtain reliable measurements of the contribution of the tyres, the wheels, the fit tolerances and the vehicle to the shake vibrations. The method is extended to produce the complex transmission factors, both direct and cross-coupling, between the forces generated by tyre and wheel non-uniformity or imbalance, and important parts of the vehicle body. These indicate which directions of input are sensitive for a particular vehicle and whether combined tyre lateral and radial force variations are important under certain conditions of relative angular disposition.
