摘　　要：近年来,国内直升机型号研制无论数量还是质量均有了较大进步,尤其是电传飞控技术的使用,在较广泛的范围内提升了直升机的稳定性和操纵性。但与此同时,在试飞中也频发中低频振动问题,频繁出现机组评述“骑马现象”,在分析过程中经常将人机耦合作为要素去关注。论文从实践的角度阐述对驾驶员诱发振荡(PIO)问题的理解、体会以及预防建议。In recent years,there has been significant progress in the development of helicopter models in China,both in terms of quantity and quality.Especially the use of fly-by-wire technology,has improved the stability and maneuverability of helicopters to a large extent in a wide range of applications.However,at the same time,there have been frequent occurrences of low-to-medium frequency vibrations in flight tests,with frequent occurrences of crew comments such as "riding a horse" phenomenon.In the analysis process,the human-machine coupling is often taken into account as a factor.This paper described the understanding,experience,and prevention of PIO problems from the perspective of pilots,which had certain practical significance.
