空气弹簧对中低速磁浮车辆动力学响应的影响研究
Study on Influence of Air Spring on Dynamic Response of Medium-Low Speed Maglev Vehicles
摘要
Abstract
[Objective]The air spring suspension system is crucial for the smooth operation of maglev vehicles.This study investigates the dynamic response of medium-low speed maglev vehicles considering detailed modeling of the air spring suspension system.[Methods]First,a nonlinear model considering the mechanical characteristics of each component of the air spring suspension system was established using the AMESim platform.Second,the validity of the nonlinear air spring model was verified by comparing simulation and experimental data of the static and dynamic stiffness of the air spring.Finally,a frame-type multibody dynamics model of medium-low speed maglev vehicles was established,considering factors such as suspension control,air spring nonlinearity,and track irregularity.The effects of different air spring modeling methods,support modes,and structural parameters on the dynamics of maglev vehicle systems were analyzed.[Results]The simulation results showed that when the vehicle passed through a curve with a radius of 550 m,the vertical ride stability indicator of the nonlinear air spring model was 1.80,which was 15.9％lower than that of the linear model(2.14).Therefore,the nonlinear characteristics of the air spring should be considered in the dynamic modeling of maglev vehicles.By comparing the dynamic responses of vehicles under four-point and six-point air spring support modes on quasi-static curves,curves with a radius of 550 m,and straight lines,it was found that the air spring support mode had little effect on the dynamic performance of maglev vehicles.In practical engineering,the choice could be made based on economic efficiency and convenience.The structural parameters of air springs had a significant impact on vehicle running smoothness.Overall,the volume of the rubber airbag should not exceed 15 L,the volume of the additional air chamber should not exceed 25 L,and the diameter of the throttle hole should be within the range of 8～16 mm.[Conclusion]The research findings can provide a reference for the design of air spring suspension systems for maglev vehicles.关键词
