制动器分析的传统方法不考虑制动蹄和制动鼓的变形,而得出不准确的制动力矩判断。虽然,这种方法对于一般的设计目的尚能满足,但在改进设计的问题上应要求较严密的分析方法。本文所述的有限元技术适用于在整个摩擦衬片面积上不一定要求保持全部接触的情况,并从逻辑上近似应用制动蹄和摩擦衬片的简单模型来决定制动鼓变形和热效应的问题,其结果已被动态试验所证实。
The traditional method of brake analysis does not take into account the deformation of the brake shoes and the brake drums and leads to inaccurate brake torque judgments. Although this method is still adequate for general design purposes, more rigorous analytical methods should be required to improve the design. The finite element technique described herein is suitable for situations where it is not always necessary to maintain full contact over the entire area of the friction lining and to determine the brake drum deformation and thermal effects from a simple approximation of the simple model of the brake shoes and friction linings The problem, the result has been confirmed by the dynamic test.
