AN ANALOGUE FR MOTOR-VEHICLE VIBRATION by

fulfillment of the requirements for the A motor-vehicle with its springs and pneumatic tires forms a very complicated vibrational system. Although the direct mathematical solution may be obtained for systems of one or two degrees of freedom, the problem of the complete vehicle is best solved experimentally. The purpose of this thesis was to design and build a mechanical analogue for motor-vehicle vibration. It consists of a body and two unsprung masses. The body is suspended by springs from the two masses which in turn are suspended by stiff springs representing the tires.-:- ~~In designing a model it is necessary to retain certain dimensionless uantities which are determined through the methods of dimensional analysis. The wheel-base of the model was chosen to be approximately on
