板簧后悬架垂直刚度影响因素的研究

摘要

建立了汽车板簧的有限元模型和后悬架有限元模型，计算分析了板簧的各个安装因素对悬架垂直刚度的影响规律，并且运用最小二乘法对分析结果进行了曲线拟合，得出了重要的规律。%The finite element model of leaf spring and the FEM of rear suspension are built in this paper, which analyzes the various installation factors on the leaf spring with affecting the vertical stiffness of suspension. And curve fitting is carried out on the analyse data, with an important rule obtained.
