无内胎全钢载重子午线轮胎不同排列钢丝圈结构的有限元分析

Finite Element Analysis on Different Bead Structure of Tubeless All-steel Truck and Bus Radial Tire

使用轮胎专用有限元分析软件TYSYS,TYABAS和TYABAS-POST,针对无内胎全钢载重子午线轮胎不同排列结构的钢丝圈进行有限元分析对比。结果表明,左斜七边形钢丝圈受力性能优于六边形钢丝圈和右斜七边形钢丝圈。室内试验结果验证了有限元分析结果的正确性。

By using finite element analysis（FEA）software for tire,TYSYS,TYABAS and TYABASPOST,the FEA comparison was made on the different bead structures of tubeless all-steel truck and bus radial tire. The results showed that,the mechanical property of left-hand heptagonal bead was better than that of hexagonal bead or right-hand heptagonal bead. The results of FEA were verified by laboratory experiments.
