虚拟现实技术在飞行器级间分离仿真中的应用

主要讨论应用虚拟现实技术进行飞行器级间分离仿真分析的方法。给出了飞行器级间分离仿真时用于控制飞行器模型运动的虚拟世界结构，并且据此建立了一个包括飞行器模型和场景模型的虚拟世界。基于Matlab和Simulink，还给出了将虚拟世界与其它的计算程序结合起来的方法，实现计算、仿真、显示一体化。基于此框架，通过流体力学、飞行力学计算以及级间相对姿态和位置的计算和分析．研究讨论了飞行器级间分离碰撞干扰问题，为级间分离方案和分离机构设计提供了依据。

Application of Virtual Reality in Flight Vehicle Stage Separation Simulation

This paper is mainly about the method of the application of virtual reality in flight vehicle stage separation simulation and analysis. The virtual world structure for controlling the motion of the flight vehicle model is presented, and hereby a virtual world including the flight vehicle model and the scene model is built up. Based on Matlab and Simulink, a method for the integration of the virtual world with other application programs is offered. As a result, the integration of calculation, simulation and visualization for stage separation simulation and analysis is realized. Under the above established framework, based on the calculations of flow fields and separation motion, and the relative attitude and position between the two stages of the flight vehicle, the separation interference problem has been studied and the work can be used to aid the design of separation mechanism.
