摘要
为了满足多片等厚叠加钢板弹簧的关键参数设计及数字化制造的需求,开发了一种多片等厚叠加钢板弹簧关键参数设计及仿真分析软件。根据截面圆弧型多片等厚叠加钢板弹簧的力学模型,建立其刚度解析计算式,并以应力强度为约束条件,建立其关键参数的设计方法。在此基础上,以Qt、ANSYS、Matlab的混合编程作为技术支持,对软件进行功能设计和GUI界面开发。最后通过软件进行实例设计,其结果显示软件设计的多片簧的刚度解析值与设计要求值同仿真值均相吻合,且相对偏差均在0.7%范围内,表明此软件可以实现多片簧的关键参数设计以及特性仿真的集成化,且设计、仿真结果可靠,对多片簧的设计具有实际推广价值。
In order to meet the requirements of key parameter design and the digital manufacturing of the multi⁃piece superposed leaf spring with equal thickness,a software of key parameter design and simulation analysis of multi⁃piece superposed leaf spring with equal thickness is developed.According to the mechanical model of multi⁃piece superposed leaf spring with circular⁃arc section and equal thickness,the analytical calculation formula of stiffness is established,and the design method of its key parameters is established by taking the stress intensity as constraint condition.On this basis,functions of the software are designed and GUI interface is developed by taking hybrid programming of Qt,ANSYS and Matlab as technical support.In the end,the software is applied to the practical example.The results show that the analytical value and the required value of multi⁃piece leaf spring stiffness designed with the proposed software is consistent to the value obtained by simulation,and the relative deviations are no more than 0.7%.It shows that the software can realize the integration of the key parameter design and the simulation characteristic of the multi⁃piece leaf spring,and the design and the simulation results are reliable,thus it has a promotion value for the design of multi⁃piece leaf spring in the practice.
