液压提升机硐室噪声的统计能量分析
Statistical Energy Analysis Approach in the Noise of Hydraulic Hoist Chamber
摘要
Abstract
The sound field of hydraulic hoist chamber with five sides sealed is studied in this paper.The acoustic models of the pump station chamber, walls, doors and the main chamber are established by applying the statistical energy analysis (SEA) theory.The loss factors, modal density and other related parameters of the models are determined and analyzed.The sound insulation and noise reduction characteristics of the walls and the doors are analyzed.The noise of hydraulic hoist chamber and driver’s console is predicted.This work has significance and guidance for the hydraulic hoist chamber’s environmental noise control.关键词
