輪胎濕抓地力之研究

The Research on Wet Grip of Tire

指導教授 : 鄭榮和

摘要


本研究是利用有限元素輪胎模型估算濕抓地力指標,並探討輪胎在不同行駛工況及各種結構設計參數對輪胎濕抓性能的影響,最後使用分析結果提出高濕抓性能輪胎的設計建議。本研究利用有限元素軟體Abaqus對規格205/55 R16的輻射胎建立有限元素模型,並參考ISO-23671輪胎濕抓地力的測試規範,建立一套濕抓地力分析流程,進行排水煞車模擬,藉此計算濕抓地力,模擬結果與試驗報告相當吻合,此結果顯示本研究之有限元素模型是合理的。利用所建立的模型探討輪胎在不同行駛工況以及各種結構設計參數對於輪胎濕抓地力的影響,如負載、胎壓、行駛速度、黏彈性質、胎紋類型等,並建立濕抓分析工具,提出設計上的建議。

This study uses finite element tire model to estimate wet grip index and discuss the influence of driving conditions and structural design parameters on wet grip performance. Based on the results, high wet grip performance tire designs are proposed. This study creates finite element model for the 205/55 R16 radial tire by the finite element software Abaqus. In order to calculate grip force on brake, the tire model refer to ISO-23671 of tire’s wet grip test regulation that is established a wet grip analysis procedure. The result is identical with the experiment, and it shows that the Finite Element model in this study is reasonable. Then the tire model is used to discuss the influence of driving conditions and structural design parameters on grip force, such as load, inflation pressure, driving velocity, viscoelasticity, tread pattern, etc. According to the result of wet grip analysis tools, we can give suggestions on it.
