Abstract
Noise research and control has gradually become one of the key factors in the development of large rotor compressor with displacement over 7 HP.Different types of noise excitation sources in rotor compressors are analyzed,of which the main factors are improved and validated by experiments.For large displacement rotor compressor with high load,the crankshaft system stability optimization is very important.3D model of the compressor is established for CAE simulation.Optimization is done on thickness of the cylinder head ring slot to achieve the contact pressure between the cylinder head and crankshaft reduction by 2%and the crankshaft deformation reduction by 1%.This significantly improves the shaft system stability during operation.Experiments also show a very positive effect on noise improvement with overall 6 dB improvement on OA value.关键词
