Abstract

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