本文采用结构矩阵分析力法,对东方红-75拖拉机车架在受到翘曲变形时的内力进行了计算与分析,系统的研究了当结构参数改变时车架内力分布的变化规律。以及该种车架强度和刚度不足的主要原因。提出了改进车架强度和刚度的实施办法。
In this paper, the structural matrix analysis method is used to calculate and analyze the internal forces of Dongfanghong -75 tractor frame under warping deformation. The variation of the internal force distribution of the frame when the structural parameters are changed is systematically studied. As well as the main reason for the lack of strength and rigidity of the frame. Proposed ways to improve the strength and stiffness of the frame.
