  避震器在車輛懸吊系統中扮演極重要的角色,為能改善車輛的操控性與舒適性,開發能隨著路面狀況來改變阻尼力大小的主動式或半主動式避震器,成為現今必須進行的工作。本論文提出使用壓電感測器與壓電致動器的新型避震器,及利用8051單晶片、A/D轉換器、D/A轉換器完成電子訊號控制電路。將單筒避震器活塞之圓片閥以壓電陶瓷、壓電薄膜及樹脂製作。經由實驗與模擬來研究圓片閥的行為,結果顯示以此圓片閥進行阻尼力控制應有極佳的效應。
  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.
