摘要:
以某型异形汽车椅弹簧为研究对象,针对其刚度特性及应力进行理论计算.利用Hypermesh与ANSYS联合仿真研究该异形汽车座椅弹簧的结构特点,并对其弹簧的刚度特性进行应力分析和强度校核.结果表明:基于弹簧串联理论得到的弹簧刚度和仿真结果更接近;汽车座椅弹簧轴向载荷与轴向变形量呈近似线性关系,刚度随着轴向力的增大而小幅增大,在满载工况下,汽车椅弹簧能满足强度要求,符合实际应用要求.利用有限元软件对弹簧进行应力分析及强度校核,并对切应力计算公式提出修正系数,使结果更加合理.
Abstract:
Taking a certain type of special-shaped automobile seat spring as the research object, theoretical calculation of its stiffness characteristics and stress was carried out. Hypermesh and ANSYS joint simulation was used to study the structural characteristics of the special-shaped automobile seat spring, together with the stress analysis and strength check of its spring stiffness characteristics. The research results show that the spring stiffness based on the spring series theory is closer to the simulation results; the axial load of the car seat spring has an approximately linear relationship with the axial deformation, and the stiffness increases slightly with the increase of the axial force. Under full load conditions, the automobile chair spring can meet the strength requirements of the actual application. The finite element software was used to perform stress analysis and strength check on the spring, and a correction coefficient was proposed for the shear stress calculation formula to make the result more reasonable.
