摘　　要：通过建立直升机飞行员负荷的评价指数,分析了不同复杂程度任务中飞行员体力、精力的要求和自身素质要求,证明了飞行员负担与驾驶操纵活动的频率存在正比关系;通过研究直升机沿着不同航迹飞行的控制量变化,引出了控制量增量幅度/梯度比的概念,建立了包含控制量幅度、频率信息的坐标图。并以坐标图中对直升机的姿态和位置变化影响较小的稳定区坐标点所占的比例作为评价飞行员负荷的指标,从而建立起包含驾驶负荷信息的指标评价体系。Using the established evaluation index of the pilot workload, demands of the mental, the physical and the own performance of the pilot are analyzed in the missions with different complexities. And the direct proportion between the pilot workload and the driving control frequency is proved to be existent. The input change along the different trajectories introduces the control increment amplitudepeak gradient ratio. The coordinate plan, including information on the control increment frequency and the amplitude, is established. The coordinate point in the stability region percentage of total points is used as the workload index. It has a greater effect on the attitude and position of the helicopter. Thus the indicator evaluation system, including the driving workload information, can be established.
