摘　　要：为更好地分析钢板弹簧刚度特性,对钢板弹簧建模方法进行了对比研究。依据钢板弹簧国家标准GB/T 19844—2005,针对某型渐变刚度钢板弹簧分别在有限元软件Hypermesh和多体动力学软件Adams中建立其有限元模型和离散梁模型,并进行了仿真,得到刚度特性。将仿真结果与试验值进行了比较。结果表明,在针对该钢板弹簧的刚度分析中,运用离散梁法得到的刚度特性更加接近试验值。According to GB/T 19844-2005, the leaf spring with gradually changing stiffness was Chinese national standard of leaf spring, a certain type of chosen as the research object to compare the superiority of the present modeling and calculation methods of the stiffness of leaf springs. The finite element model and the discrete beam model of the research object were established by using the finite element software Hypermesh and the multi-body dynamics software Adams, respectively. Then, the stiffness of the leaf spring was obtained through simulation. At the same time, the traditional methods of calculating the stiffness of leaf springs through common curvature and concentrated load were also used to calculate the stiffness of the research object, respectively. We compared the simulation stiffness and the calculated stiffness with the test stiffness, and found the stiffness of the discrete beam model is closer to the test stiffness for this leaf spring.
