虚拟轨道列车抗侧倾液压互联悬架研究
Research on Anti-roll Hydraulic Interconnected Suspension of Virtual Rail Trains
摘要
Abstract
The three-module,eight-axle virtual rail train is selected as the research object.A proposal is made to replace the original workshop axle bridge with an anti-roll hydraulic interconnected suspension system.The applicability of the anti-roll hydraulic interconnected suspension to the virtual rail train is then explored.A physical model of the anti-roll hydraulic interconnected suspension is constructed based on AMESim.The influence of hydraulic parameters on system stiffness is explored through theoretical and simulation methods.A vehicle dynamics model is built in SIMPACK software.The accuracy of the simulation model is verified by comparing the results with the actual modal frequency test of the vehicle body.By reasonably setting the hydraulic parameters of the anti-roll hydraulic interconnected suspension and building an AMESim/MATLAB/SIMPACK machine-hydraulic coupling joint simulation model,the influence of the anti-roll hydraulic interconnected suspension on the dynamic performance of the train is explored.The simulation results show that under straight driving conditions,the lateral stability of train operation is improved by the anti-roll hydraulic interconnected suspension.In the snake test and single lane change conditions,a large nonlinear roll stiffness is provided by the anti-roll hydraulic interconnected suspension,the roll angle of each vehicle is reduced,and the anti-roll stability of the train is improved.关键词
