It is necessary to separate the multiple resonance frequencies of a vehicle body from outstanding peaks of excitation spectrum to reduce the road induced noise of cars. A vehicle body is always excited by the transmitted forces from a chassis system, and worse the transmitted forces change in real time with road surfaces. Therefore, we suggest that semi-active control of the vibration characteristics of a car body is useful for reducing road induced noise of cars. In this paper, we derived a design method of joint stiffness for simultaneous placement of multiple resonance frequencies. Specifically, we have focused our efforts to make an eigenvalue of a kernel compliance matrix to zero at the assigned natural frequencies by changing the joint stiffness connecting a main system and a subsystem. Consequently, it is enabled to control the multiple resonance frequencies of a whole structure with low computational cost. |
