摘要:

针对直升机机身振动水平过大的问题,设计了一种带斜角橡胶件的新型主减液弹隔振器。通过动力学建模计算,分析了液弹隔振器传递特性,讨论了液弹隔振器设计参数对隔振效率的影响。对新型液弹隔振器性能进行了校核,结果表明该设计在各向减振效率高于60%的情况下仍具有高的静刚度,适用于直升机工程应用。

Abstract:

To address big vibration level of helicopter fuselage, a new fluid elastomer vibration isolator with special cant connection is designed. Based on the dynamic model and simulation, the load transmission characteristics and parameter influence of the fluid elastomer vibration isolator are analyzed. The results of performance calculation show that the design can increase static stiffness under the assumption that vibration isolation efficiency in all directions above 60%, and applicability to engineering applications.

Key words: helicopter, gearbox isolation, fluid elastomer vibration isolator, transmission characteristic, dynamic modeling
