摘要

为了综合评估直升机主减液弹隔振系统的隔振效率,建立液弹隔振系统与机体耦合动力学仿真模型,通过频响分析得到了液弹隔振系统的隔振效率;采用悬吊法进行了主减液弹隔振系统装机地面振动试验。仿真和试验结果表明:液弹隔振系统在航向、侧向和垂向综合隔振效率在70%以上。研究结论对液弹隔振系统进一步优化设计提供了技术支持。

Abstract

In order to evaluate synthetically the vibration isolation efficiency of main gearbox fluidelastic isolation system in the helicopter, the fluidelastic isolation system and fuselage coupling dynamic simulation model was established. The vibration isolation efficiency of the fluidelastic isolator system was obtained by frequency response analysis. The suspension method was applied to carry out the ground vibration test for the helicopter with the fluidelastic vibration isolation system. The simulation analysis and test results showed that the comprehensive vibration isolation efficiency of the fluidelastic vibration isolation system along the heading, lateral and vertical direction,was more than 70%. This conclusion could provide technical support for optimal design of the fluidelastic vibration isolator system。
