铁道车辆主动悬挂系统模糊控制策略研究

Research on Fuzzy Control Strategies of Active Suspension System of Railway Vehicles

车辆悬架的作用是承载车身和车轮之间的力,为车轮和车身之间的力和力矩传递提供渠道,避免来自路面的力直接冲击车身,有效缓解冲击荷载导致的振动,确保车辆安全、舒适行进,保证行车的平稳和安全。车辆平顺性和操纵稳定性是目前车辆动力学中还没有完全解决的问题,在铁道车辆中,悬架电控技术可以针对该问题进行解决,目前这方面的研究备受关注,一些学者开始探究悬架模糊控制器设计和振动悬架系统仿真设计方案。该文以铁道车辆为例,探究基于整车系统模型的新型模糊控制方法,设计模糊控制器,完善控制系统设计,采取有效的控制算法,确保车辆主动悬挂仿真模型构建,为整车模型模糊控制实现提供思路与参考。

The role of the vehicle suspension is to carry the force between the body and the wheels,provide a channel for the transmission of force and torque between the wheels and the body,avoid the force from the road directly impacting the body,effectively relieve the vibration caused by the impact load,ensure that the vehicle travels safely and comfortably and ensure smooth and safe driving.Vehicle ride comfort and handling stability are problems that have not been fully solved in vehicle dynamics at present.In railway vehicles,suspension electronic control technology can solve this problem,this research has attracted much attention at present,and some scholars have begun to explore the suspension fuzzy controller design and vibration suspension system simulation design scheme.Taking the railway vehicle as an example,this paper explores a new fuzzy control method based on the vehicle system model,designs a fuzzy controller,improves the control system design,adopts an effective control algorithm,and ensures the construction of the vehicle active suspension simulation model,so as to provide ideas and references for the realization of the fuzzy control of the vehicle model.
