摘要

接觸變形與磨耗是在一般機構中常見的複雜行為與現象，本研究結合動力學、接觸理論與磨耗分析等三個領域的主要物理參數關係式，透過電腦的快速運算能力，嘗試建立一個整合的接觸模擬分析流程。首先以赫茲接觸理論及有限元素分析為基礎，求得物體在接觸面上的壓力分布，並建構動態接觸下的等效避震器模型，搭配剛體動力學的運動分析，以及Archard的磨耗方程式，以分析離合器系統在接觸變形與磨耗作用下的性能表現變化。期望能藉此建立機械元件接觸與磨耗行為的整合分析能力，以為實務設計與系統改良時的參考。

Part contact deformation and wear are sophisticated phenomena frequently encountered in machines. Facilitated by high-speed simulation of modern computers, this research is aimed to integrate physical models of dynamics, Hertzian contact, and Archard’s wear equation for the analysis of clutch performance under both effects. The approach utilizes Hertz contact theory and finite element analysis to establish the equivalent contact model and surface contact pressure for Archard’s equation and dynamic motion analysis. It is hoped to create a framework for integrated analysis of contact and wear between parts, and enhance the ability of practical design applications and improvement.
