基于频域的驾驶员操纵负荷评估方法

为进一步增强直升机飞行品质中的主观负荷评价的准确性和可靠性,建立一种可用于描述飞行员工作负荷的客观指标,采用时频分析的方法,建立了基于频域的驾驶员操纵负荷三维尺度模型,并通过飞行试验对模型的量化结果进行了对比。通过量化三维尺度模型可以对驾驶员操纵负荷的主观评价提供数据支撑,辅助飞行员进行飞行品质的评价。

In order to further enhance the accuracy and reliability of subjective load evaluation in helicopter flight quality,an objective index which can be used to describe pilot workload is established by using the method of time-frequency analysis,a three-dimensional scale model of pilot control load based on frequency domain is established,and the quantitative results of the model are compared by flight test.The quantitative three-dimensional scale model can provide data support for the subjective evaluation of pilot load and assist pilots in the evaluation of flight quality.
