摘要
针对载重汽车对承载性、平顺性及可靠性等多方面的要求,提出了一种以橡胶弹簧和钢板弹簧共同作用提供弹性力的复合悬架。考虑簧片间的非线性接触和摩擦,在HyperMesh中建立了复合悬架的有限元模型,并利用RDAIOSS对其在不同载荷作用下的应力分布和变形进行了分析,得出了复合悬架应力分布和刚度特性变化的初步规律,为复合悬架虚拟设计及重型车辆的轻量化设计提供参考依据。
In order to satisfy the requirements of heavy vehicle in loading capacity, riding comfort and reliability, a composite rub- ber suspension is proposed in this paper. In this suspension ,the rubber spring and the leaf spring work together to supply the spring fore. First,an accurate FEM model for the composite sus- pension is built in HyperMesh software with consideration of the nonlinear contact and friction between spring leaves. Then,the stress distribution and deformation with different loads are analyzed by using RADIOSS and the results can be applied to its strength design. Finally ,some primary principles of the stress distribution and the variation of stiffness of the composite rubber suspension are obtained, which provides reference basis for virtual design and lightweight design of the vehicle composite rubber suspension.
