摘要

線控煞車系統較一般傳統式油壓煞車系統有重量較輕、裝設容易與反應較快之優點，目前發展中之線控煞車系統包括電子控制液壓系統之電子液壓煞車系統(EHB)與完全電子控制之電子機械煞車系統(EMB)。本研究主要針對電子機械式線控煞車系統之作用器進行設計分析，首先藉由學術資料之收集與整理規劃出線控煞車系統之設計任務與要求，並利用專利資料之收集與整理執行機構之構造分析與設計，擇定系統之架構後利用動力源與運動傳遞機構之數學模型進行機構之運動及動力分析與設計，最後產出線控煞車系統作用器之最佳概念。
此外，本研究藉由Pro/Engineer Wildfire 2.0電腦輔助設計軟體，建立其3D Model，並應用Pro/Assembly模組中Mechanism指令之模擬功能，對所設計之電子機械式煞車機構進行動態模擬。經確認煞車於機構作動過程中並無干涉情形發生後，再利用ANSYS 11.0進行應力與應變之分析，以確定該設計煞車機構所需之強度。

The Brake-by-Wire system is more weight reduction, easy installation, and quick response than the traditional hydraulic brake system. The developed Brake-by-Wire systems include electronic hydraulic brake system (EHB) which hydraulic system is electronic controlled and electronic mechanical brake system (EMB) fully electronic controlled. This project aims at the mechanism design of EMB. First, the design requirements of EMB can be defined in terms of the analysis of academic data. The structure analysis and design of EMB will be executed based on the collection and deduction of patent data. Then, the mathematical models of power source and transmission mechanism are used to analyze the EMB system’s kinematic motion and static force.
In addition, using the computer aid program with the Pro/Engineer Wildfire 2.0 to build up the 3D model; while the Mechanism instruction of Pro/Assembly is applied to simulate the movements of subject electro-mechanical brake in order to ensure no interferes are involved or occurred. Furthermore, ANSYS 11.0 is used to analyze stress and stain, so as to confirm the intensity of the electro-mechanical brake designed.
