摘要
根据冲裁模压力中心的理论求解公式,提出了利用AutoCAD面域的逻辑运算求解压力中心的方法,用实例给出了该法的求解步骤,并将其结果与理论计算结果相比较,两个方向的绝对误差均少于0.01mm,相对误差均少于0.02%。
According to theoretical solution formula of pressure center for stamping die, the approach for solving the pressure center by use of logic operation of AutoCAD region has been put forward. The steps of this method have been given by example. By comparing this result with the theoretical calculation result, the absolute error in both directions is less than 0.01mm and relative error is less than 0.02%.
