摘要:

针对航空发动机转子振动精准抑制对装配工艺的需求,提出了一种虑及多转速多级盘结构转子虚拟装配平衡优化方法。以多级盘转子试验台为对象建立了转子动力学模型,在各级盘残余不平衡量及转子原始振动已知的情况下,通过仿真模型进行虚拟装配。以转子各测点的残余振动以及转子整体不平衡力和不平衡力矩为优化目标,采用多重优化算法寻找各级轮盘装配角度的优化方案。最后在3盘转子系统试验台上进行了试验验证,结果表明,使用该方法可使转子在宽转速范围内振动均有所下降,其中最大下降幅度为85.75%。本文结果可为航空发动机多级盘结构转子装配提供方法和技术支撑。

Abstract:

A multiple optimization method for virtual assembly balance of multi-disk rotors with multi-speed is proposed to meet the requirement of precise rotor vibration suppression in engine assembly. We establish a simulation model of the multi-disk rotor test rig, through which the virtual assembly is conducted, with known magnitude and phase of the residual unbalance of each stage disk and the original rotor vibration. Taking the residual vibration of each measuring point of the rotor and the overall unbalanced force and moment as the optimization objectives, the multiple optimization algorithm is used to find the optimization scheme of the mounting angle in each stage of the assembled disks. Experiments are performed on the test rig of the three-disk rotor system. The results show that this method can reduce the rotor vibration in a wide speed range with a maximum reduction of 85.75%. This study provides important methodological and technical support for engine rotor assembly.

Key words: multi-disk rotor, virtual assembly, multi-speed, balance, multiple optimization
