机车车辆动力学计算模型的可视化研究

机车车辆的动力学动态仿真系统一般包括模型建立、模型计算、模型显示３部分。文中提出了基于三视图ＣＡＤ设计思想，可视地将机车动力学仿真模型初始数据链附着在图形界面上，从而建立起机车车辆动力学仿真的几何模型。这便于模型建立和修改，也便于将模型向仿真计算传递。同时，在模型计算结果的基础上，提出了基于三维动画的模型动态显示方法，能逼真地模拟模型计算的结果，有效地检验了机车车辆动力学模型的相关性能，这两项研究

Visualization of Computing Model of Locomotive Dynamics

A locomotive dynamics simulation system generally consists of model building, model calculation and model display. This paper puts forward a CAD method that is based on three view drawing. In this method, the initial data chains of a locomotive dynamics simulation model can be visually attached to a graphics interface to build the geometry model of the locomotive dynamics simulation, which is convenient for model building and modifying, and also convenient for the model to be passed to its simulation calculation. Meanwhile, on the basis of the results of the model calculation, a three dimensional animation based model dynamic displaying method is proposed, which can realistically simulate the model simulation results and efficiently check the properties of the locomotive dynamics model. These two research items can further improve the integration of locomotive dynamics simulation systems.
