摘要
研究了一种少自由度飞行模拟实验台,该实验台由动平台、静平台和二者之间3条互成120°的PRS欠约束主动支链组成。提出了一种基于尺度参数平面的多评价指标尺度综合方法,将实验台模拟性能、刚度、操作性能和铰链最大转角作为评价指标,研究并讨论了各尺度参数变化对各评价指标的影响规律。在尺度参数平面内绘制出各评价指标的等值线,根据影响规律和等值线综合出满足各评价指标的尺度参数区域,进而在满足各评价指标的尺度参数区域内确定实验台的尺度参数,最后通过算例验证了该尺度综合方法的有效性。
A less DOF experiment platform of flight simulator was studied,which is composed of a moving platform,a static platform and three PRS active branch chains between them. The active branch chains had 120° between each other. Based on scale parameter plane,a multiple-evaluation-indexes dimensional synthesis approach was proposed in this paper. It was taken the simulation performance,stiffness,operating performance and maximum angle of hinge as evaluation indexes. The influence laws of scale parameters to evaluation indexes were studied and discussed. In the scale parameter plane,the contour of evaluation indexes was drawn. According to the influence laws and the contour,the scale parameter region was confirmed and the region was satisfied the range of evaluation indexes. Then the scale parameter was determined in the region. Finally,the effectiveness of the method was proved by the example.
