摘　　要：大型压缩机转子实际运行过程中转速很高(可达60000r/min),而齿轮啮合、气流冲击总会给转子带来一定的扰动。这就导致了滑动轴承在这种高速轻载工况下不得不面对一系列稳定性问题。文章提出一种压缩机用滑动轴承实验设计方案。设计的实验台系统包括实验轴承及实验转子、驱动装置、加载装置、数据采集和润滑装置5个部分,并设计了常规工况、超速工况、参数识别、故障诊断、轴承性能评判等实验内容。同时结合有限元软件仿真分析设计了低速可行性验证实验为压缩机用滑动轴承实验设计方案提供可行性验证和相应的测试准备。During the actual operation of the rotor of a large compressor,the rotating speed is very high(up to 60,000r/min),and the gear meshing and airflow impact will always bring some disturbance to the rotor.As a result,the sliding bearing has to face a series of stability problems under the condition of high speed and light load.An experimental design scheme of sliding bearing for compressor is presented in this paper.The designed experimental platform system includes five parts:experimental bearing and experimental rotor,driving device,loading device,data acquisition,and lubrication device.The experimental contents such as conventional working condition,overspeed working condition,parameter identification,fault diagnosis and bearing performance evaluation are designed.At the same time,combined with the simulation analysis of finite element software,the low speed feasibility verification experiment is designed to provide feasibility verification and corresponding test preparation for the experimental design scheme of sliding bearing for compressor.
