摘　　要：为了提高球形补偿器球体的加工效率、表面质量并降低生产成本,提出采用液压胀形来代替传统的焊接和锻造成形的加工工艺,通过有限元模拟仿真研究了最大胀形压力、左右冲头的轴向进给量和摩擦因数这三个主要影响因素对球形补偿器球体成形的影响,根据仿真结果得出一组最佳工艺参数:最大胀形压力为25 MPa,左冲头进给量为15 mm,右冲头进给量为20 mm,摩擦因数为0.125,在这组参数下得到的球体最小壁厚值为1.523 mm,最大减薄率为23.85%。采用这组最佳参数进行实验验证,实验获得的球体最小壁厚值为1.502 mm,最大减薄率为24.90%,实验结果与仿真结果误差较小,球体成形质量好。In order to enhance the action competence,exterior quality,and concentrate production costs of the spherical compensator sphere,hydraulic bulging is proposed to replace the traditional welding and forging forming process.Through finite element simulation,the influence of three main influencing factors,namely maximum bulging pressure,axial feed rate of left and right punches,and friction coefficient,on the configuration of the globular compensator sphere is studied.Based on the replication results,a set of optimum process parameters are obtained:maximum bulging pressure of 25 MPa,left punch feed of 15 mm,right punch feed of 20 mm,friction coefficient of 0.125.Under these parameters,the minimum wall thickness value of the sphere obtained is 1.523 mm,and the maximum thinning rate is 23.85%.Using this set of optimal parameters for experimental verification,the minimum wall thickness value of the sphere obtained in the experiment is 1.502 mm,and the maximum thinning rate is 24.90%.The error between the experimental results and simulation results is small,and the quality of the sphere forming is good.
