Optimization Simulation Analysis of Noise Reduction Based on the Mechanism of Noise Generation and Transmission in Turbine Compressors

Turbine compressors are highly efficient power compressors widely used in fields such as chemical engineering and refrigeration. However, there is vibration during compressor operation, and the vibration noise is amplified through the transmission path of the compressor structure itself, which has adverse effects on the production environment and the health of operators. Therefore, this article analyzes the mechanism of vibration noise generation and vibration propagation in turbine compressors, and constructs a vibration and vibration transmission path model. Based on the above two models, by collecting and separating sound, the generation of vibration at the source can be reduced. At the same time, improving the vibration transmission path can effectively reduce the transmission of vibration noise in turbine compressors. Then, by studying the sound radiation characteristics of the compressor housing, it helps to reduce the vibration of the compressor. The path of noise propagation, Finally, by constructing sound radiation characteristics and modal analysis characteristics, the outer shell of the turbine compressor is optimized to determine the reasonable distribution positions of reinforcement ribs and rib plates, thereby reducing shell vibration and radiation noise.
