从降低旋翼动载荷向机身传递的基本目标出发，研究了新型旋翼／机身隔振装置的基本设计思想，给出了设计原则及方法，介绍了反共振装置、波纹板的设计及试验的关键。台架试验表明：该装置能同时实现对桨毂五个交变力素的隔离，其隔振效率及重要指标均达到设计要求
Starting from the basic objective of reducing the dynamic load transfer from the rotor to the fuselage, the basic design concept of the new rotor / fuselage vibration isolation device is studied. The design principles and methods are given. The design and test of anti-resonance device and corrugated board The essential. The bench tests show that the device can realize the isolation of the five alternating forces of the hub at the same time, and the vibration isolation efficiency and the important indexes all meet the design requirements
