臺灣博碩士論文加值系統

本論文主要在研究應用可調式避震器發展出半主動式懸吊系統，本文所分析之可調式避震器段數調整型式屬於段續式調整，共分32段，主要結構為將32段阻尼調變機構，並經由步進馬達轉動此阻尼調變機構，藉以改變孔口面積，達到調變阻尼係數。本文研究使用不同控制器來發展半主動式懸吊系統，以改善汽車舒適性與安全性；此外，為了求出避震器之阻尼係數，本文設計一新型的測試機構來建立避震器之阻尼資料庫以提供控制器設計時使用。最後為了來達成即時控制之半主動懸吊系統架構，本文使用CAN bus系統來建構分散式控制系統，並進行系統之整合。

In this research, a study of semi-active suspension using an adjustable shock absorber vibration control is presented. There are thirty-second kinds of damping selections in the adjustable shock absorber. The main structure of the adjustable shock absorber includes an adjusting element within a conventional shock absorber. A stepping motor is driven to rotate the adjusting element. The motor actuates the adjusting value to change the amount of hydraulic fluid which bypasses the damping passage between two hydraulic chambers to achieve the desired damping coefficient. In this paper, the continuous damping controllers are studied to improve ride comfort and driving safety. Furthermore, a new testing rig is designed to obtain the damping coefficients and to implement our method. Finally, the CAN bus based control architecture is developed and used to implement this study.
