摘要
轧制力和轧制力矩是楔横轧汽车半轴轧机设计中的重要参数,由于楔横轧多楔成形半轴时主楔和侧楔之间相互制约,轧制过程中轧制力和轧制力矩的变化复杂.针对典型汽车半轴,采用LS-DYNA有限元软件,对楔横轧多楔轧制汽车半轴进行了数值模拟,获得了轧制过程中各因素对轧制力和轧制力矩的影响规律.
Rolling force and rolling moment are the important parameters when cross rolling wedges mills forming automobile semi-axes was designed. The changes of rolling force and rolling moment are complicated in the rolling course due to the mutual restriction relation between main wedge and side wedge in the process of multi-wedge cross rolling wedges （MCRW） forming automobile semi-axes. The LS-DYNA finite element soft-ware was adopted to simulate the process of MCWR rolling automobile semi-axes by setting up a finite element model. The rule was obtained that the rolling force and rolling moment change with every factor in the rolling course.
