Abstract: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.
