本刊81年第3期谢根深同志的“弹压零件模具弯曲半径的计算”一文,对这类零件的模具设计很有价值。我们采用文中介绍的方法计算Y系列电动机波形垫圈模具的合理弯曲半径,其结果基本符合要求。 原文对计算的关键——求解超越方程(原文中(3)式) 1-h/(ro)=cosc/(ro)(h,c为已知参数) This issue 81 81 No. Xie Gen deep comrades, “the calculation of bending radius of elastic parts die,” a article, mold design of such parts of great value. We use the method described in the article to calculate the Y series motor waveform washers reasonable bending radius, the results basically meet the requirements. The original calculation of the key - solving transcendental equation (((3)) 1 -h / (ro) = cosc ​​/ (ro) (h, c is a known parameter)
