【摘要】 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。更多还原

【Abstract】 The inner forces of the frame subjected to warping deformation are calculated and analyzed in the way of structural matrix moment method. A systematic study of the inner force distribution of the frame with changing structural parameters and the important reasons for the insufficiency in strength and rigidity of the frame is carried out. A method of improving the strength and rigidity of the have been suggested in this paper.更多还原
