列车纵向动力学仿真图形系统

A Simulate-Graphic System of Train Longitudinal Dynamics

本文讨论列车纵向动力学仿真图形系统的计算机硬件设备和软件结构。为了提高铁路运输能力,我们利用计算机图形技术,结合计算机仿真程序,进行列车纵向动力学的研究工作。该仿真图形系统可以模拟不同工况下各种列车编组型式的运行情况,根据需要将仿真数值结果绘制成二维或三维图形,以分析列车纵向动力学各种参数的变化情况,合理选择运行方案。通过与有关试验资料对比分析,列车纵向动力学仿真图形系统有良好的可靠性和实用性,在大秦铁路线建设工程中得到应用。

The hardware and software of SGS (the Simulate-Graphic System of train longitudinal dynamics) is discussed in this paper To increase railroad trafflc volume, we have studied train dynamics and programmed SGS, combining numerical simulation methods with computer graphic techniqne SGS can well simulate train ope rations, and analyze train performances. The results of SGS are good in reliability, and it has been applied in the oew Da-Oin heavy haui line.
