摘　　要：为研究减速带几何特性对汽车振动响应的影响,优化悬挂参数以提升驾驶舒适性。基于Simulink软件对汽车通过减速带时的振动响应进行仿真分析。仿真结果表明,汽车通过减速带时的振动响应受减速带几何特性的显著影响。减速带过高时,车辆的振动加剧且存在剐蹭风险;减速带过低时,则无法达到足够的减速效果。通过调整车辆悬挂系统的参数(如阻尼系数)并选择合适的减速带几何尺寸,可有效降低汽车通过减速带时的振动水平,从而优化驾驶舒适性。本研究为减速带设计及车辆悬挂调校提供了理论依据,有助于平衡减速效果与乘坐舒适性需求。To study the influence of the geometric characteristics of speed bumps on the vibration response of automobiles and optimize suspension parameters to improve driving comfort.conducts a simulation analysis of a vehicle’s vibration response when passing over speed bumps using Simulink software.The simulation results indicate that the vibration response is significantly influenced by the geometric characteristics of the speed bump.When the speed bump is too high,the vehicle experiences intensified vibrations and a risk of scraping;when the speed bump is too low,it fails to provide sufficient deceleration.By adjusting suspension system parameters(such as damping coefficient)and selecting appropriate speed bump dimen-sions,the vibration level during passage can be effectively reduced,thereby optimizing ride comfort.This analysis provides a theoretical basis for the design of speed bumps and vehicle suspension tuning,which helps to balance the deceleration effect and ride comfort requirements.
