Abstract
Modern passenger cars are equipped with measurement technology to control the function of engine and different safety systems. In addition, the requirement for improved ride comfort is growing which means that the vibrations of the vehicle has to be minimized. One source of vibrations are unbalanced rotating parts of the vehicle due to wheels and drive shafts. To compensate such unbalances the present technology is based on measurements off the road and the dynamic behaviour of the vehicle system is not taken into account. This paper presents a method based on the parameter identification of a multibody system model of the vehicle to determine the value and angular location of compensation weights for the wheels to achieve an overalJ compensation of harmonically excited vibrations on the road. Thus, the complete dynamic vehicle system driving on its rolling wheels is taken into account.
