测试测量设备虚拟维修样机行为建模研究

摘要

It classes VMPTE's behavior as operation part and response part and makes an research on their behavior modeling method.Analyzed operation part's behavior restriction and realised operation part's rotatation and transition behavior with Vega function.According to the response part's characteristic, it classes response part as number display, indicator light and graph display; It shows numbers with SWITCH node using cgital diode lighting as reference.And then using GL-LINE-STRIP arithmetic realised the real-time graph display on base of OpenGL Performer.%将测试测壁设备虚拟维修样机划分为操作部件类和响应部件类,对其行为属性建模方法进行研究.分析了操作部件行为约束关系,基于Vega函数对操作部件的旋转和平移运动方式进行了实现;根据测试测量设备仪表显示特点,将响应部件类划分为数字显示、指示灯亮灭以及波形绘制等基本功能模块;借鉴数码管亮灭控制方法,使用视景仿真建模软件Multigen Creator中的SWITCH节点控制七段数码管的亮灭以显示数字;采用空间绘制曲线的GL-LINE-STRIP算法,基于OpenGL Performer实现了波形的动态显示.
