摘要
基于有限元分析软件对24.00R35全钢工程机械子午线轮胎胎圈裂口进行仿真分析,分析胎圈裂口机理,结合分析结果对胎圈部位轮廓设计进行优化,并试制成品轮胎进行验证。结果表明:胎圈部位过渡圆弧设计和防水线高度对胎圈部位受力影响较大;胎圈侧部采用垂直线设计、胎圈部位轮廓与轮辋曲线互不干涉时,胎圈部位与轮缘的接触压力和剪切应力相对较小;适当的防水线高度可以减小轮胎防水线位置的接触压力和剪切应力;采取优化设计可以明显降低胎圈部位裂口风险,避免轮胎的早期失效,延长轮胎的使用寿命。
The bead crack of 24.00R35 all-steel off-the-road radial tire was simulated by using finite element analysis method and the mechanism was analyzed.The bead contour design was then optimized based on the analysis results,and the trial-produced tires were tested for verification.The results showed that,the design of transition arc and the height of waterproof line had great influence on the stress of the bead.The contact pressure and shear stress between the rim and the bead part were relatively small when the bead side was designed with a vertical line and the contour of the bead part and rim curve did not interfere with each other.Furthermore,appropriate height of waterproof line could reduce the contact pressure and shear stress at the position of waterproof line.The optimized design could significantly reduce the risk of bead cracking,avoid early tire failure,and thus extend the service life of tires.
