摘　　要：针对车辆二系悬挂系统阻尼力并不能适应性地衰减由高速化、轻量化导致的车体振动激增,致使乘坐舒适性恶化等问题,提出一种基于模糊控制的轨道车辆二系悬挂参数半主动控制策略,通过Simulink和Simpack联合仿真分析,进行半主动控制优化,得出优化后的阻尼力,此研究为有效地降低车辆横向、垂向振动,提高车辆运行品质的相关研究提供参考。The damping force of vehicle secondary suspension system can not adaptively attenuate the vibration surge of the vehicle body due to high speed and lightweight,and the ride comfort deteriorates.Aiming at the above-mentioned problems,a semi-active control strategy of secondary suspension parameters of rail vehicles based on fuzzy control is proposed in this paper.Through the co-simulation analysis of Simulink and Simpack,semi-active control optimization is performed to obtain the optimized damping force.The study provides a reference for effectively reducing the lateral and vertical vibration of vehicles,and improving the vehicle running quality.
