摘要
并联六自由度运动系统是飞行模拟器非常重要的组成部分。其本质
是由数字计算机实时控制并能提供俯仰、滚转、偏航、升降、纵向和侧
向平移的六自由度瞬时过载仿真设备。
本文从研制者的角度出发,评述了研制飞行模拟器六自由度运动系
统所需的关键技术及其国内外的研究进展。结合样机设计与制造的实践
经验,提出亟需解决的若干理论与技术问题,以及解决这些问题的可行
途径。
本文以为仿真工具,建立了六自由度运动系统机构的数学
模型,对其进行了动力学分析。特别针对位置正解的复杂性,利用求位
置反解的方法来求解位置正解。另外,本文详细地介绍了运动模拟的逼
真度。文章中介绍的运动控制算法可为飞行员提供逼真的运动感觉,从
而为飞行模拟器的运动系统提供可靠的依据。

六自由度飞行模拟器运动系统设计研究

Parallel 6- DOF motion system (Stewart Platform) is an extremely
ponent of the flight simulator. Its basic principle is a
equipment used in instantaneous overloading imitation, which offers the
6- DOF of pitching, rolling and turning, leeway, departing and landing,
portrait and abeam translation controlled synchronous puters .
This ments on the vital technology in the development of
the 6- DOF motion system of the flight simulator and the study results in
this area by now. It figures out the theories and technological problems
that needed to be solved and the feasible solutions to these problems
bining the practical experiences in designing and
manufacturing the model machine.
This article establishes a mathematical model of 6- DOF motion system with
MAT LAB as the emulating tool, makes dynamics analysis. Especially, aiming at
plexity of forward position, this article uses the method of solving
backward position to solve the forward position. In addition, this article
introduces the fidelity of motion simulation in detail. The arithmetic of
movement control introduced in this article can provide a vivid sense of motion
for the pilot, so as to provide a reliable reference for the moving system of the
flight simulator.
