摘　　要：对钢板弹簧式后悬架的运动原理进行了研究,应用向量的方法建立了钢板弹簧的数学分析模型。并且应用Matlab数学计算软件编写了通用的计算程序,方便地求解出板簧上各个硬点的坐标,从而进行了传动轴长度和角度的校核计算。经过对比分析发现,其计算结果与传统的传动轴跳动图的结果完全一致,证明了该分析模型正确、可靠。This paper studies the motion of leaf spring rear suspension, and establishes the mathematical model of leaf springby using vector method. And a general calculation program is programmed using Matlab software to calculate the coordinatesof the key points on the leaf spring model easily. Thus, the length and angle of the drive shaft can be calculated. Throughcomparison and analysis, it is found that the calculated results are in good agreement with the results of the traditionalgraphic method, which proves that the model is correct and reliable.
