Abstract: The paper discusses a basic simulation way on founding a front suspension simulation model. It applies on method of multi-body dynamics and uses virtual prototyping technology software ADAMS building up Macpherson suspension entity mold. It analyzes the relations between a Macpherson suspension system and wheel alignment characteristic through kinematics simulation, and obtains the changing trend of the wheel alignment parameters. This provides theoretical foundation with further optimization design.
Key words: Macpherson Suspension; Kinematics Simulation; ADAMS
1. Introduction
Suspension system is a key part for cars, and has decisive effect on car drivability, stability, fortability. Because of its characteristics of simple structure, low cost and space economy, Macpherson suspension has e the most popular independent suspension since its emergence. Hence, the kinematics analysis of Macpherson suspension has great significance. ADAMS (Automatic Dynamic Analysis of Mechanical System) is a simulation software of mechanical system used most widely in the world. Based on the ADAMS virtual model technology, the automobile suspension is regard as a multi-body system which parts connect and motion each other. With the help of ADAMS/View, this paper established multi-body dynamics model of Macpherson front suspension of some car which is increasingly wide used in modern car, and the effects of suspension parameters when wheel travel or turn were studied. The ADAMS entity numeric suspension ics simulation provides an efficient and updated tool for developing suspension system.
