| Summary: | 碩士 === 國立屏東科技大學 === 車輛工程系所 === 100 === The purpose of this study is to analyze the Macpherson front suspension system and twist beam rear suspension system by discussing the effect of suspension geometry to vehicle behavior when the vehicle steering. Through establish the full vehicle chassis suspension model system software ADAMS, the parameters such as vehicle speed, radius of curvature, and the stiffness of spring have been chosen for simulating and analyzing the vehicle behavior of constant-radius cornering. From the results, we can explore the performance of cornering and the effects of the suspension design parameters. Among these parameters, we choose the vehicle understeer coefficient, front wheel steering angle, yaw rate gain, and the lateral acceleration gain, etc. for further verified by theoretical calculate which performed by MATLAB. The results manifested the validity of the model and simulation.
