随机线加速度运动环境生成原理及实现

The Creating Principle and Realization of Random Linear Acceleration Movement Environment

在大气层中飞行的飞行器，往往易受大气扰动的影响。大气紊流现象可用随机过程的理论和方法来描述，其对飞行器的影响反映为飞行器含随机加速度分量。本文利用并联驱动六自由度平台来模拟随机线加速度运动环境，可实现空间六自由度模拟。试验结果表明，该平台有能力实现随机线加速度运动环境。文章也提出了用平台模拟该环境需解决的一些问题。

When an aircraft flies in atmosphere, it is often effected by atmosphere disturbance. The phenomena of atmosphere disorderly current can be described using random process theory, and its effect on the aircraft can be regard as that the aircraft acceleration contains random component. This paper used parallel 6 degree of freedom platform to simulate random linear acceleration movement environment. The platform can realize 6 degree of freedom movement simulation in space. The experiment results show that the platform has the ability to realize random linear acceleration movement environment. And the paper also presents that several problems should be settled to simulate the environment using the platform.
