| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 92 === Shock absorber plays an important role in the vehicle’s suspension system. For improving vehicle’s controllability and riding comfort, development of active or semi-active shock absorber to control the damping force for different road conditions is the necessary work now. In this thesis, we propose a new type of shock absorber using a piezoelectric sensor and actuator. We use 8051 chip, D/A converter and A/D converter to finish the electronic signal control circuit. The disk valve on the piston of the monotube shock absorber is made of piezoceramic, piezofilm and epoxy. Both simulation and experiment were performed to study of the disk valve. The results show the good promise for using this disk valve to control the damping force.
