Bending and torsional coupling study of rolling-piston compressor valves

Abstract

In this paper, a model of a rolling compressor valve with one end fixed horizontally is presented and simulated using the flow-solid coupling (FSI) method for rolling rotor type compressors. Optimisation of the diagonally cut section can effectively reduce the pressure pulsation of the compressor. The results show that the valve blade generates coupled vibrations of bending and torsion, and the slant-cut structure improves the frequency of pressure pulsations, increases the stability of the compressor valve blade, optimises the compressor structure and reduces the pressure pulsations of the compressor.
