列车纵向运动的计算机仿真

Simulation of Train's Longitudinal Movement

本文介绍了列车纵向运动的计算机仿真方法,建立了计算机仿真的常规模型,稳态模型、准动态模型和动态模型,并概括了各种模型的基本假定、核心内容和适用条件。

In this paper, the methods for simulating train movement in the longitudinal direction are introduced, the mathematical models, including con- ventional, stable, dynamic and quasi-dynamic models, are set up. The paper also sums up the general hypotheses, main problems, and applicable situations for each model. The positive result shows that the quasi-dynamic model is more practical to simulate train's movement and maximum coupling force in real time on micro-computers. The last part of the paper briefs on some achievements in the field of railroad profile research.
