Theoretical Analysis of Revolving Vane Compressor Vibrations

摘要

The revolving vane (RV) compressor is a relatively new rotary compressor design and many of its performancerncharacteristics would have to be evaluated. Vibration of compressors is one of these aspects and this paper presentsrnthe theoretical analysis for the vibration characteristics of the RV compressor. The analysis is done by dividing therncompressor into two components – the rotational vibration of the cylinder-rotor assembly, and the resulting torsionalrntwist of the stationary shell housing. The unique approach of using Lagrange’s equations to formulate the equationrnof motion for the complex cylinder-rotor assembly is presented here.
