采用上限元法 ,在分析金属流动规律的基础上 ,将齿轮正挤压时变形区划分为 9个区域 ,并根据各区域的金属流动特点给出了金属流动规律的表达式 ,并通过试验进行了验证
Based on the analysis of the law of metal flow, the upper limit element method is used to divide the deformation zone when the gear is squeezed into nine zones. According to the characteristics of the metal flow in each zone, the expression of metal flow rule is given and tested by experiments Verified
