Abstract

Purpose

Elastic rings served as the elastic supporting elements which have been extensively used in the aeroengines for maneuverable planes with high overloading. However, under extreme conditions, the elastic ring contacts the bearing seat, causing elastic ring failure. Therefore, it is necessary to optimize the matching parameters of the elastic ring in order to suppress the occurrence of elastic ring failure under harsh working conditions.

Design/methodology/approach

In this paper, a rotor system supported by elastic rings is researched and a multi-objective parameter matching method of elastic ring is proposed, considering the elastic ring failure, rotor system’s frequency forbidden zone and rotor system’s dynamic response. Then, the particle swarm optimization algorithm is used to dynamically constrain the parameter matching space and obtain the ideal solution for the elastic ring parameter matching.

Findings

By analyzing the elastic ring’s matching results (different unbalanced forces and disk masses), the relationship between the trend of Pareto front changes and rotor system parameters is studied. In addition, the rotor system’s dynamic characteristics before and after parameter matching are analyzed.

Originality/value

This article provides guidance for the design of elastic rings by matching the parameters of elastic rings.

利用粒子群优化法实现转子系统弹性环的多目标参数匹配

目的弹性环是一种弹性支撑元件，被广泛应用于航空发动机中的高过载机动飞机。然而，在极端条件下，弹性环会接触到轴承座，导致弹性环失效。本文以弹性环支撑的转子系统为研究对象，综合考虑弹性环失效、转子系统频率禁区和转子系统动态响应等因素，提出了弹性环的多目标参数匹配方法。研究结果通过分析弹性环的匹配结果（不同的不平衡力和盘质量），研究了帕累托前沿变化趋势与转子系统参数之间的关系。此外，还分析了参数匹配前后转子系统的动态特性。
