摘要
空气弹簧对中低速磁浮列车悬浮系统性能和车辆运行平稳性有着重要的影响,若用弹簧阻尼系统代替空气弹簧建立磁浮车辆的动力学模型,则存在模型误差大、仿真精度差等问题。该文以磁浮列车用空气弹簧为研究对象,基于Simpack动力学分析软件,建立了带附加气室空气弹簧的动力学模型,并对其进行了试验验证,在此基础上研究了节流孔直径、附加气室容积对空气弹簧动力学的影响。建模思路为磁浮列车车辆动力学建模提供了新的方法,仿真结果为空气弹簧的优化设计提供了参考。
The air spring has an important influence on the performance of the suspension system and the running stability of the maglev train.If the dynamic model of the vehicle is established by using the spring damping system instead of the air spring,there will be problems such as large model error and poor simulation accuracy.The paper takes the air spring for maglev train as the research object,the dynamic model of the air spring with auxiliary chamber is established based on the Simpack dynamic analysis software,the model is verified by experiment.On this basis,the dynamical behavior of the air spring with different diameter of orifice and the volume of auxiliary chamber is studied.The modeling idea provides a new method for vehicle dynamics modeling of maglev train,and the simulation results provide a reference for the optimal design of the air spring.
