摘要

摘要: 研究了一种三自由度飞行模拟器驱动平台的尺度综合方法。该驱动平台由动平台、静平台、3条UPS无约束主动支链和1条PU恰约束从动支链组成,并提出从动支链由气动支撑单元构成,通过压缩气体承载主要负载,以提高驱动平台的模拟性能。基于Rayleigh商和向量的性质,提出了基于向量2范数的模拟性能评价指标,通过单调性分析讨论了各尺度参数对驱动平台刚度、操作性能和模拟性能的影响规律,并通过该影响规律寻求评价函数的最优解。最后通过算例验证了该方法的有效性。

Abstract: An approach was proposed for the dimensional synthesis of a 3-DOF driving platform of flight simulator.The driving platform was composed of a moving platform,a static platform,three UPS unconstrained active branch chains and a UP driven branch chain. The main load was born by the driven branch chain which was composed of pneumatic support unit through the compressed gas in order to improve the simulation performance of driving platform. The simulation performance was presented to be taken as an evaluating index which was based on the vector 2-norm with the aid of the characters of Rayleigh quotient and vector. The influence law of scale parameters on the stiffness,operating performance and simulation performance of the driving platform was discussed through monotonic analysis and it was adopted to seek the optimal solution of the evaluation function. The effectiveness of the method was proved by the example.
