Design of Vibration Isolators Optimizing Riding Comfort

抄録

This paper is concerned with the synthesis of vibration isolators optimizing the riding comfort of vehicles under random excitations. Optimum control theory in frequency domain is applied to solve the optimizing problems. The theoretical implementation has been accomplished for single- and two-degree-of-freedom systems. As design examples, the optimum vibration isolators for the systems with white noise foundation excitations and with roadway excitations are synthesized. The optimum vibration isolators thus obtained can only be mechanized with active elements rather than conventional spring-dashpot elements. It is, however, possible to set up the configuration approximately with passive elements. It is found that the riding comfort of vehicles with the optimum vibration isolators is considerably better than that with conventional passive isolators.
