新型高效的悬架架构设计方法

Innovative and effective method of suspension concept design

传统的悬架架构设计方法使用多体动力学仿真进行大量试错,因此对时间及人力需求高,但效果不稳定。针对该问题建立的新方法首先应用新型解析算法设计悬架硬点,再应用基于ADAMS及MATLAB二次开发的自动化软件设计弹性件。相比传统方法,新方法效率提升约8倍。新方法还包含一套性能参数管控标准,能系统性地判断135项悬架运动学及整车动力学性能参数的优劣,以此指导设计。相比传统方法依靠设计人员经验判断参数优劣,新方法更全面、精准和稳定,更能确保设计质量。

The traditional method of suspension concept design requires a large number of trials and errors by using multibody simulations.It has thus high demand for time and manpower but the results are unstable.To solve these problems,a new method containing two steps has been developed.A novel analytical method is first applied to design hardpoints,and then elastic parts are designed using a secondary developed software based on ADAMS and MATLAB.Compared with the traditional method,the new method improves the development speed by about eight times.The new method also includes a control standard of 135 parameters of suspension kinematics and vehicle dynamics.It can judge the pros and cons of concepts and thus guide the design.Compared to the traditional method for parameter judgment,which relies on the experience of designers,the new method is more comprehensive,accurate and stable,leading to a higher design quality.
