摘要
为了直观地研究重载列车动力学参数性能,克服直接对数值数据进行对比分析效率低的缺点,提出了以多图层图形化的方法显示动力学参数变化规律,实现了多车辆、多类型动力学参数的对比分析,并利用该方法采用面向对象编程语言开发了仿真绘图工具软件。该软件具有图形曲线的绘制、图形坐标轴移动、曲线的放大和缩小、曲线线型和颜色控制等功能,且已经嵌入到重载列车动力学仿真系统中,工程实际应用表明了该方法的有效性,并为工程项目中实验数据的分析提供了可视化的工具。
To intuitively study the dynamic parameter performance of loaded train and overcome the inefficient flaws by directly analyzing and contrasting of numerical value data, a graphical method based on multi-layer structure is put forward. It is used to show the change regularity of dynamic parameter. It implements contrastive analysis of the dynamic parameter of multi-vehicle and multi-type. A simu- lation drawing tool software by utilizing the method is developed based on object-oriented programming language. The functions of drawing curve, moving horizontal axis, enlarging or diminishing curve and the control of color and line-style of curve are implemented in the system. It is embedded in the dynamic simulation system of loaded train. The efficiency of the presented method is demonstrated by practical application and a visual drawing tool is presented for the analysis of experimental data in project.
