一种直升机旋翼桨毂旋转面内振动调整方法
摘要：
本发明属于直升机动力学技术领域，涉及一种用于直升机旋翼桨毂旋转面内振动调整的方法，其方法包含两部分，分别为桨毂摆振阻尼器的调整和桨毂配重片的调整：在旋翼桨毂旋转面内振动偏心力达到60-100kg或者舱内垂向振动速度值达到0.6-1ips时采用桨毂摆振阻尼器调整；在旋翼桨毂旋转面内振动偏心力小于60kg或者舱内垂向振动速度值小于0.6ips时采用桨毂配重片调整。本发明的方法可以克服目前单一调整方式的不足，确保直升机的振动环境保持在舒适的水平。
摘要（英）：

The invention belongs to the technical field of helicopter dynamics, and relates to a method for adjusting vibration in a rotating surface of a rotor hub of a helicopter. The method comprises two parts, specially, the adjustment of a hub shimmy damper and the adjustment of a hub weight stack are carried out, when the vibration eccentric force in the rotating surface of the rotor hub reaches 60-100kg or the speed value of the vertical vibration in a cabin reaches 0.6-1 IPS, and the hub shimmy damper is adopted to adjust; when the vibration eccentric force in the rotating surface of the rotor hub is less than 60 kg or the speed value of the vertical vibration in the cabin is less than 0. 6g IPS, and the hub weight stack is adopted to adjust. According to the method, the defects of a currentsingle adjustment mode can be overcome, and the vibration environment of the helicopter is ensured to be kept at a comfortable level.
