城市轨道车辆模态分析与噪声预测
Analysis of Vibration Modes and Prediction of Interior Noise of Urban Railway Vehicle
摘要
Abstract
he finite element model (FEM) of the structure and interior acoustic cavity of an urban railway vehicle is established for modal analysis. The body structure is improved, and its vibration modes and the sound field distribution at different frequencies actuated by the bogie in the urban railway vehicle are compared with those of the unimproved structure. Some conclusions are obtained for noise abatement of urban railway vehicles.关键词
