煞車系統在不當的駕駛習慣或保養習慣時,容易造成煞車來令片或碟盤磨耗不均現象,而導致振動、噪音的問題。本論文是針對煞車來令片因磨耗而引起的煞車系統振動噪音作研究。 論文中應用有限元素套裝軟體模組HyperWorks對煞車系統主要元件和次系統建模並作分析,模擬預估煞車來令片磨耗情形,分析結果與文獻值比較,趨勢相近;再以磨耗所造成的厚薄不均的情況,做煞車系統振動噪音分析,最後改變煞車系統相關設計變數,來改善煞車系統振動噪音問題。 研究結果顯示,應用不同熱處理能加強表面強度、降低磨耗現象,進而改善改善煞車系統振動噪音現象。改善後,煞車系統振動幅度可有效減少78%,煞車來令片磨耗降低15.3%,針對現有市售車的設計改善是很直接且容易達成的。
Harsh driving behaviors or poor vehicle maintenance can easily cause un-uniform wear on the brake pad or disc and lead to vibration or noise problems of the brake system. This research focuses the brake vibration that is due to the pad wear. The study uses the commercial finite element code package, HyperWorks, to create the major components and sub-systems of a brake system, and to analyze and to predict the wear of the brake pad. The analysis results of this study are compared with the data of literature. They show good consistency with each other. Design improvement is made by choosing different heat treatment for the pad to enhance the surface toughness. The wear of the pad is reduced by 15.3%, and the vibration amplitude of the brake system is improved around 78%. It is a quick, easy and practical way to improve the brake vibration and pad wear problems for the vehicles which are on the market.
