摘 要 平顺性是现代高速、高效率汽车的一个主要性能,汽车平顺性直接影响到人和车辆汽车平顺性的好坏直接影响到乘员的舒适性、工作效能和身体健康Abstract Ride a modern high-speed, high efficiency, a key performance cars, automobile ride a direct impact on people and vehicles. Car ride will have a direct impact on passenger comfort, efficiency and physical health. Due to peoples car comfort and safety requirements gradually increase, while the cars suspension system also made high demands. Therefore suspension design related to the merits of car use is an important theoretical and practical application of significance. The graduation project is the senior research sedan Chrysler 300 C suspension system. Therefore, the design of the front suspension suspension system ranging from a long double arm independent suspension, ranging from long double arm independent suspension can guarantee a good car driving stability, for the car before the High Suspension by the widespread adoption. After the suspension multi-link independent suspension, five-link independent suspension with excellent maneuverability and a higher response, with remarkable smoothness of the traffic. According to the models and suspension forms to determine the parameters of a suspension, a suspension of the natural frequency, the suspension stiffness, static and dynamic deflection deflection. And to calculate the size of the selected components and flexibility to stress checking. By damping and unloading of the largest absorber identified the main dimensions. Finally, the horizontal direction and Wen Dinggan design. CAXA mapping software were used before and after the suspension of the assembly and parts plans. Matlab software to use the ride suspension system and the stability of the programming movement analysis, demonstration of the system design of reasonable accuracy, to meet the actual needs.
