基于Vega的弹射救生可视化仿真系统研究

Application of Vega in Aircrew Escape System Simulation

工作于应急离机状态的弹射救生装置是一个复杂的动态系统,其工作环境复杂、不确定因素多。如何利用仿真技术来研究系统的动态特性一直是仿真工作的难点。提出了一种基于面向对象的连续系统仿真方法,并将连续系统仿真和基于Vega的视景仿真相结合共同构成可视化仿真系统。各对象成员负责自己的初始化,并根据全局仿真类传递的控制信息和自己封装的数学模型完成自身状态的转换。仿真类根据系统状态来控制完成数据的交换,在获得系统仿真数据的同时获得直观的可视化结果。

Aircrew escape system is a complex dynamic system with complex workingcondition and a lot of uncertain factors. The difficult point is how to investigate the dynamic characteristics using simulation technologies. This paper puts forward a method of object - oriented continuous system simulation, and conbines the continuous system simulation with video simulation of vega to construct video simulation system. The object initializes itself repectively and changes its state according to the control information and mathematic model of global simulation class. Simulation class completes data exchanges according to system state controlling information so as to get simulation system data and video frequency at the same time.
