摘要

针对某直升机主减机匣的振动噪声问题，对主减传动系统模型进行动力学仿真分析，求解了弧齿锥齿轮副高速传动时产生的动态啮合冲击力；以主减机匣为研究对象，基于阻尼减振机理，分析了轴承座添加泡沫铝阻尼材料对机匣振动的影响。求解机匣振动响应，研究轴承座不同厚度的泡沫铝材料对机匣固有频率、模态阻尼比的影响；分析了阻尼层不同安装位置对轴承座阻尼结构减振效果的影响。结果表明，主减速器啮合频率处机匣的振动加速度值减小14.89%；在轴承座处添加阻尼材料可以增大机匣模态阻尼比，有效地抑制机匣的振动。

Abstract

Aiming at the vibration and noise problem of a helicopter main reduction casing，the dynamics simulation analysis of the main reduction transmission system model is performed to solve the dynamic meshing impact force generated by the spiral bevel gear during high-speed transmission. Taking the main reducer as the research object，based on the damping vibration reduction mechanism，the influence of adding foam aluminum damping material to the bearing seat on the vibration of the casing is analyzed. The vibration response of the casing is solved，and the influence of the aluminum foam material of different thicknesses on the natural frequency and modal damping ratio of the casing is studied. The influence of different installation positions of the damping layer on the vibration reduction effect of the damping structure of the bearing seat is analyzed. The calculation results show that the vibration acceleration peak of the casing at the meshing frequency is reduced by 14.89%. Adding damping materials to the bearing seat can increase the modal damping ratio of the casing and effectively suppress the vibration of the casing.
