Abstract

Automotive pneumatic tyre plays an important role for vehicle suspension system.Development process of tyre involved experiments which are time consuming and expensive, hence increase the tyre development cost. In order to overcome this problem, many other methods have been implemented. One of these methods is Finite Element Analysis. This aims of this project are to develop a simplified 185/70 R14 pneumatic tyre model to study road/ tyre interaction using Finite Element Method by using ABAQUS software. This project started with 2D axisymmetric tyre modeling to perform rim mounting and inflation analysis followed by 3D tyre model by revolving the 2D mesh developed. The footprint and steady state rolling analysis are performed to study the behavior of tyre when in contact with the road surface during loaded and rolling condition where this analysis is very complicated that involved high experiment cost. Instead of carry out experiment, the computational method is used to study the tyre behavior. Real tyre components are considered in this project which included one carcass, two belts and rubber matrix. In axisymmetric model, element group of CGAX3H and CGAX4H from ABAQUS are used to define the element for rubber matrix and the tyre reinforcement are represented as rebar in surface elements, SFMGAX1 are embedded into the continuum elements. After the analysis of tyre using CAE, the results are validated with result from previous research.
