基于Simulink和VRML的铁道车辆运行可视化仿真

Visual running simulation of railway vehicles based on Simulink and VRML

铁道车辆在铁轨上的运动是一个复杂的运动学过程。对铁道车辆在轨道上的运行特点和运动仿真方案进行分析,确定车辆模型基本运动控制数据的生成流程。采用三维CAD建模和VRML建模语言,建立铁道车辆和运行场景的可视化仿真模型,利用Simulink实现铁道车辆模型的运动控制与仿真。在开发的铁道车辆运行可视化仿真平台上实现较为逼真的运行可视化仿真。

It was a complex kinematical procedure that railway vehicles ran on the truck. After analysis on running characteristics and simulation approaches of railway vehicles, the data production process of basic motion control was presented for railway vehicle model. Though 3-D modeling technique and VRML modeling language, the virtual models and running scene of railway vehicles were constructed. The motion control and simulation of the railway vehicle models were achieved by Simulink. A vehicles were constructed. The motion control and simulation of the railway vehicle models were achieved by Simulink. A visual running simulation platform of railway vehicles was developed, and the running simulation was realistic on the platform.
