摘要
　　本研究將以電腦輔助工程軟體，建立一套正時鏈傳動系統模擬之方法與流程，並分析液壓張緊器元件，對整體系統之影響性。於模擬方面，依實體之研究機台為基礎，並以汽車引擎怠速時之轉速950轉為模擬之設定條件，藉由電腦輔助工程軟體LMS Motion建立一套正時鏈傳動系統，並透過此初步的系統模型，進行靈敏度分析，了解設定參數對系統之影響性，找出影響系統的關鍵參數，以及排除較無相關性的參數，藉以輔助模型修正。於實驗量測方面，主要量測動軌之振動、液壓張緊器推出力，以及鏈輪轉速，分析時域與頻域下之結果，使實驗量測與模擬結果得以相互驗證，增加模擬之正時鏈傳動系統可靠度；最後，以液壓張緊器元件為探討重點，針對與液壓張緊器相關之供油壓力、供油油品黏滯性、洩油縫隙與單向閥大小，四個影響系統之變數作探討，並以系統之傳動誤差為指標，作為區分系統優劣之判斷標準，並提出液壓張緊器建議之設計方向。

ABSTRACT
　In this thesis, a timing chain driveline simulation method and process is established by using the computer-aided engineering (CAE) software, and the influences of the whole system caused by the hydraulic chain tensioner is also investigated. In the simulation part, the timing chain driveline simulation model is shown by the computer-aided engineering software LMS Motion based on the experiment machine, and the engine speed is set at 950 rpm which is the car engine idle speed as the simulation condition. Through this preliminary system model, the sensitivity analysis is applied to understand the influences of the parameter setting and to find out which are the most significant parameters to assist us in modifying the system model. In the experiment part, the measurements of the guide vibrations, hydraulic tensioner force, and the sprocket speed are applied. By comparing the experiment and simulation results through time domain and frequency domain analysis, the timing chain driveline simulation model can be verified to increase the reliability. Finally, parameters of the hydraulic chain tensioner of the timing chain driveline such as : oil supply pressure, oil viscosity, leakage gap, and check valve size are investigated, and the transmission error is taken as criteria for judging the merits of the system. In the end, according to the results, some hydraulic chain tensioner design directions are given.
