Research progress on design and experiment of squirrel-cage elastic supports in aircraft engines
摘要
Abstract
Squirrel-cage elastic supports are crucial vibration-damping support structures in aircraft engine rotor sys-tems,capable of supporting the rotor,effectively regulating critical speeds of the rotor system,reducing rotor system vibration,and simultaneously serving for monitoring rotor vibration and axial loads.Therefore,they are widely applied in aircraft engine rotor systems.This paper summarizes and prospects the structural design and experimental tech-niques of squirrel-cage elastic supports from aspects including functional roles,optimized design,stiffness and strength,testing and monitoring,and developmental trends.During the structural design of squirrel-cage elastic sup-ports,considerations must be given to stiffness,strength,and testing monitoring,involving optimization of structural parameters among single and multiple objectives.The analytical methods,finite element methods,and experimental methods for calculating and testing squirrel-cage elastic support stiffness and strength are elaborately introduced.Addi-tionally,the paper discusses vibration monitoring and axial force measurement technologies for squirrel-cage elastic supports,conducts research and analysis on other atypical squirrel-cage elastic support types such as folded-type,bearing outer ring integrated-type,variable stiffness,variable damping,and controllable squirrel-cage elastic sup-ports.These findings provide significant reference and enlightenment for the design and experimental studies of squirrel-cage elastic supports with diverse application scenarios and functionalities.关键词
