全钢载重子午线轮胎成型中胎圈最佳落点的仿真研究

以两种规格轮胎为研究对象，对全钢载重子午线轮胎成型中胎圈最佳落点进行仿真研究。通过建立有限元仿真模型对全钢载重子午线轮胎成型中扇形块的锁紧过程进行仿真，并将仿真结果与实测数据进行对比，验证了有限元仿真模型的准确性；通过调整扇形块的横向位置，从扇形块径向锁紧力和胎圈横向位移两个角度确定了胎圈的最佳落点。

Simulation Study on Optimal Bead Landing Point in Building of All-steel Truck and Bus Radial Tire

A simulation study was conducted on the optimal bead landing point in the building of all-steel truck and bus radial tire，using two specifications tires as research objects.The locking process of the sector block in the building of all-steel truck and bus radial tire was simulated by establishing a finite element model，and the accuracy of the finite element simulation model was verified by comparing simulated results with the measured data.By adjusting the lateral position of the sector block，the optimal bead landing point of the tire was determined from the radial locking force of the sector block and the lateral displacement of the bead two angles.
