VEHICLE DYNAMICS ANALYSIS BY 'ANALYTICAL METHOD OF EQUIVALENT LINEAR SYSTEM USING THE RESTORING FORCE MODEL OF POWER FUNCTION TYPE'

The 'Analytical Method of Equivalent Linear System using the Restoring Force Model of Power Function Type', used as a method of non-linear vibration analysis of vibration systems demonstrating viscoelastic characteristics, has been used to analyze steering torque characteristics and vehicle yaw rate response and quantify steer feel. Data from actual vehicles driven at high speed in the on-center area has been analyzed. It is shown that the method is able to clearly express the frequency dependency of individual vehicle characteristics.
