摘要: 少片变截面钢板弹簧刚度设计是轻型车悬架性能设计的重要基础。针对少片变截面两级刚度钢板弹簧采用理论计算、有限元仿真与试验测试相结合的方法研究某轻型车钢板弹簧刚度设计。结果表明,理论计算可以高效完成校核悬架布置及初步刚度匹配;有限元仿真能模拟详细设计特征、接触及摩擦等因素;试验测试则表明刚度仿真结果具有较高的精度。基于刚度测试验证的仿真模型,有助于进一步研究结构强度特性。

Abstract: The stiffness design of less-sheet taper leaf spring is an important and fundamental work for the performance design of lightweight vehicle suspension. A combination of theoretical calculation,finite element simulation,and experimental testing was used to study the stiffness design of less-sheet taper leaf spring for a lightweight vehicle. The results indicate that theoretical calculations can efficiently complete the verification of suspension layout and preliminary stiffness analysis. The finite element method can simulate detailed design features,contacts and friction. And the finite element simulation results have a high agreement with the experimental results. A verified simulation model based on stiffness test is helpful for further study on the comprehensive performance of structural strength.

Key words: two stage stiffness, leaf spring, taper, finite element method
