輪胎胎紋磨耗分析 輪胎胎紋磨耗分析 邱進東 德霖技術學院 機械系助理教授 摘要 輪胎胎紋磨耗評估大都以實車做道路測試為主，約需要花兩至三個月的時間讓車子跑兩至三公里， 才能知道輪胎胎紋的磨耗程度，是一項費時的工作，因此有必要建立一套模擬方法作為新開發輪胎的磨 耗預估。輪胎的性能如磨耗、操控、噪音及傳動等，都與輪胎的接地壓力有關。 本論文擬以有限元素法模擬輪胎胎紋接地壓力以做為磨耗預估，分析模型採輪胎整體模型包含胎紋 部分。主要工作內容為考慮輪胎為各種不同的 材料層，建立輪胎結構部分的三維複合材料模型。由輪胎 平面胎紋圖建立三維輪胎胎紋模型及胎紋網格分割。胎紋與結構部分以膠合(glue)方式做接觸演算，輪胎 受車重影響胎紋與地面為接觸邊界條件，計算 出胎紋靜態接地壓力分佈，做為靜態磨耗評估。由分析結 果建立胎紋異常模耗的評估方式，預估不均勻磨耗所可能的導致原因，及建議改善方式。 關鍵詞：輪胎、接地壓力、磨耗、有限元素法 Wear Analysis of Tread Pattern for Pneumatic Tire Jinn-Tong Chiu Assistant Professor, Department of Mechanical Engineering, De Lin Institute of Technology Abstract The wear prediction of tire tread pattern is a time-consuming work and almost from road test of real tire at present. The test tire is traveled about 2 to 3 kilometers in two months or three to obtain the wear of tread pattern. Thus building up a simulation procedure to predict the tread wear is a necessary technique for a new tire design. Tire performance such as tread wear, handling, noise, traction, etc., is determined ultimately in the tire footprint. The finite element method (FEM) is applied to obtain the footprint pressure and predicted the tread wear in this paper. The 3D FEM model includes the structure and tread pattern of tire. The material behavior of tire is considered as a composite material model for the cord-plies and Mooney-Rivlin model for rubber layers. Developing the 3D geometric model and mesh of tread pattern from 2D tread pattern.The 3D FEM mesh of tread pattern is contacted with the structure of tire by the glue algorithm. The whole model of tire is contacted with ground subject to t
