应用MSC MARC有限元分析软件优化27.00R49巨型工程机械子午线轮胎带束层结构

Optimization of Belt Structure of 27.00R49 Giant Off-The-Road Radial Tire by MSC MARC Finite Element Analysis Software

以27.00R49巨型工程机械子午线轮胎为例,应用MSC MARC2021有限元分析软件建立轮胎静态有限元模型,研究A方案带束层结构光面轮胎与带花纹轮胎的静负荷受力情况;B方案为A方案带束层结构的优化方案,对两种方案带束层结构的各层受力和轮胎接地印痕进行有限元分析,并与实测结果进行对比。结果表明,B方案带束层结构比A方案更优,有利于减少轮胎胎肩脱层问题。

Taking 27.00R49 giant off-the-road radial tire as an example,the static finite element model of the tire was established by using MSC MARC2021 finite element analysis software,and the static load force of a smooth tire and a tread-patterned tire which both had the scheme A belt structure was studied.Scheme B belt structure was then obtained through the optimization of the scheme A.The force on each belt layer and the tire footprint of the two schemes were analyzed by finite element analysis,and compared with the measured results.The results showed that the belt structure of scheme B was better than that of scheme A,and the problem of tire shoulder delamination could be reduced with the scheme B belt structure.
