Compatibility Design Method of Low Vibration and Light Weight by Using Experimental SEA

Abstract

For compatibility of low vibration and light weight in high-frequency problem, a design guideline is proposed based on a structural design process using experimental SEA for reducing structure-borne sound on machinery. The basic concept of the proposed method is taking consideration into reduction of vibration energy at target subsystem by preventing propagation to the target and concentration of vibration energy into another subsystem simultaneously. In this paper, the structural design process is reviewed, and compatible design guideline for low vibration and light weight is proposed. Then the proposed method is applied to reduce vibration and lighten power control unit used in hybrid automobile.
