摘要/Abstract

摘要： 为了真实地模拟高速列车在运行时的各种姿态,在Stewart六自由度运动平台的基础上,采用VC++编程语言开发了高速列车模拟驾驶动力学仿真系统和模拟操纵界面。建立了高速列车系统动力学模型,头车为纵向、横向和垂向耦合的详细模型,其他车为质量块纵向模型。在仿真过程中动力学模型根据线路数据和司机的操作指令实时更新,采用新型显示积分方法“翟方法”对动力学模型进行求解。计算出高速列车头车车体各自由度在不同工况及控制条件下的响应,将车体加速度作为六自由度运动平台的驱动,形成半实物半虚拟的模拟驾驶动力学仿真平台。采集了实际车辆车体运行加速度数据与仿真进行对比,相关结果较接近,并应用于模拟驾驶系统进行司机培训。

Abstract: In order to truly simulate the moving postures of the high-speed train at run time, based on six degrees of freedom Stewart motion platform, dynamics simulation system and simulation operation interface are developed by VC++ programming language. The dynamics model of high-speed train system is presented in this paper, whose first vehicle is a detailed coupled model including longitudinal, lateral and vertical DOF (Degree of Freedom), and other vehicles are the mass models only with the longitudinal DOF. In the process of the simulation, the dynamics model is updated in real time according to line data and driver's operation, and then dynamics model is solved by a new display integral method (zhai method). The responses of all DOF of high-speed train head car body in different working conditions and control conditions are calculated. The body acceleration is applied to drive the six DOF motion platform forming a simulated driving dynamics platform, which is both physical and virtual. The availability is carried out based on the dynamic simulations and field test results. The simulated driving dynamics system is successfully applied to drivers training.
