摘要: 軋制力和軋制力矩是楔橫軋汽車半軸軋機設計中的重要參數,由于楔橫軋多楔成形半軸時主楔和側楔之間相互制約,軋制過程中軋制力和軋制力矩的變化復雜.針對典型汽車半軸,采用LS-DYNA有限元軟件,對楔橫軋多楔軋制汽車半軸進行了數值模擬,獲得了軋制過程中各因素對軋制力和軋制力矩的影響規律.Abstract: 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.
