轧钢机械教材中介绍的采利柯夫万向接轴叉头强度计算方法,只能对某一确定断面作强度计算,没有断面应力与断面位置的函数式,因此,要找出危险断面和最大应力就需要对许多断面重复计算,再进行比较。本文用解析方法导出断面应力与断面位置的函数式,通过求导而得出危险断面位置和最大合成应力,不仅省去重复计算工作量,而且提高了计算结果和精度。 Rolling machinery textbooks introduced Cloverkop universal joint yaw strength calculation method, only for a certain section for strength calculation, there is no cross-section stress and cross-sectional function of the location, therefore, to find the dangerous section and the largest Stress requires repeated calculations on many sections and then compared. In this paper, we derive the formula of cross-section stress and cross-section position by analytical method, derive the position of dangerous cross-section and the maximum synthetic stress by derivation, which not only eliminates the need of repeated calculation work, but also improves the calculation results and accuracy.
