【摘要】 以轴段半径、轴段长度、轴肩过渡圆半径作为参考因素,以危险点的最大应力作为评价指标,对一种接触式径向加载机构横轴的结构参数进行优化。应用有限元分析参数灵敏度,考虑设计经济性,采用控制变量法对轴段半径r和轴肩过渡圆半径R_d进行定量分析。在满足轴的体积尽可能小的情况下使得危险点的应力得到了显著降低,最后对横轴进行了安全系数和可靠性校核。更多还原

【Abstract】 In this paper, the shaft radius, the length of the shaft section and the radius of the shoulder radius are taken as the reference factors. The maximum stress of the dangerous point is used as the evaluation index to optimize the structural parameters of the horizontal axis of a contact radial force loading mechanism. Using the finite element analysis parameter sensitivity, considering the design economy, the control variable method is used to quantitatively analyze the shaft radius and the shoulder radius. When the volume of the shaft is kept as small as possible, the stress at the dangerous point is significantly reduced,and finally the safety factor and reliability of the horizontal axis are checked.更多还原
