摘要
在坡道地段的运动仿真是高铁在整个运动仿真中的重要部分.为了研究高铁在坡道地段的运动仿真,本文提出了基于虚拟现实的高铁运动仿真模型.首先构建高铁模型和地形;然后将高铁抽象成绳体模型,从动力学角度分析高铁在坡道地段上的受力情况和运动状态;最后在虚拟现实引擎Unreal Engine中进行相关蓝图节点的连接,利用其提供的完整套件、实时高逼真的渲染效果,将其应用在高铁的仿真中.对研究高铁线路选取设计、模拟运行以及列车速度等参数和地形的适应关系等提供了很好的手段和方法,使模拟效果与列车实际运行状态最大程度匹配,同时也给相关的其他研究提供了参考.
Motion simulation on ramp is an important part of the whole motion simulation of high-speed railway.In order to study the motion simulation of high-speed railway on ramp,this study puts forward a simulation method based on virtual reality.First,the high-speed railway model and terrain are constructed.Then,high-speed railway is abstracted into rope model,and the force and motion state of high-speed railway on ramp are analyzed from a dynamic point of view.Finally,related blueprint nodes are connected in virtual reality engine Unreal Engine,and it is applied to the high-speed railway simulation using the complete suite and real-time high-fidelity rendering effects provided by it.It provides a satisfied means and method for studying the design of high-speed railway line selection,simulated operation,and the adaptability of parameters such as train speed and terrain,so that the simulation effect can be matched with the actual operation status of the train to the maximum extent,and also to provide reference for other related studies.
