Abstract
The vibration of a rolling piston type rotary compressor for air-conditioning use is analyzed numerically and experimentally. Multibody dynamic analysis methods to predict the vibration are given. The compressor is modeled as a multibody system composed of bodies, joints, and force elements. Experimental results are shown to compare with simulation results. A sensitivity study using different variables that affect the compressor vibration is also carried out. It is found that the mass of the weight balancer plays an important role in acceleration.
