Radial Tire Construction Design Method Based on Finite Element Simulation

摘要

The simulation of 295/80R22.5 tire building process from tire building to cuing was developed using ABAQUS software,which covered four stages:gluing of components on main drum,gluing of components on auxiliary drum,building process of greentire and shaping process of green tire.Results showed that material distribution of the simulated structure had good cohetence with the realtire structure.Therefore,the tire building process simulation can he used to judge the rationality of tire construction design and to determine the shapes of different tire components.In order to optimize the construction design,a reverse simulation method was proposed to design the semi-product components such as apex,tread,and shoulder pad.The semi-product components determined by utilizing the reverse simulation method were assembled again into a tire.Results show that the simulated material distribution is consistent with the mterial distribution of design tire,which proves effectiveness and reliability of the reverse simulation method.
