摘要

阻尼件是叶盘结构中起减振作用的主要部件

而阻尼件的干摩擦散乱失谐会影响其在叶盘振动中的减振作用。本文利用谐波平衡法与快速傅立叶变换技术

对具有非线性干摩擦力的叶盘受迫响应进行了数学建模

仿真分析了叶盘系统在各种耦合、粘性阻尼比、干摩擦强度、干摩擦散乱失谐程度等参数影响下的受迫响应规律。研究结果显示

叶盘系统在弱耦合和粘性阻尼比较大的情况下

干摩擦散乱失谐会导致叶盘共振幅值显著增大。

Abstract

Dampers in bladed disks are main components for reducing vibration.The dry friction disorder among those dampers can affect their damping performance.In this paper

the harmonic balance method and the technique of fast Fourier transmission were employed to simulate the forced response of bladed disks with nonlinear dry friction.The characteristics of bladed disks with disordered dry friction were investigated and analyzed under different coupling

viscous damping ratio

dry friction strength and the degree of dry friction disorder.The study indicates that the disorder of dry friction can significantly increase the resonant response of bladed disks

especially in the system with weaker coupling and larger viscous damping ratio.
