叙述了对轮对压装机进行力学分析的必要性,采用UG建立了轮对压装机上连接梁的三维实体模型,对压装机上连接梁在压装工况下的受力情况进行了分析,分别求出了上连接梁的应力分布和变形并进行了比较。结果表明上连接梁在压装工况下的最大应力均小于许用应力,证明了上连接梁的强度和刚度满足轮对压装的强度要求。 The necessity of mechanical analysis of the wheelset press is described. The three dimensional solid model of the wheelset press connected beam is established by using UG, and the stress of the connecting beam on the press is analyzed. The stress distribution and deformation of the upper connecting beam were calculated and compared respectively. The results show that the maximum stress of the upper connecting beam under the loading condition is less than the allowable stress, which proves that the strength and rigidity of the upper connecting beam satisfy the strength requirements of the wheelset.
