Acoustic Optimization Design of Vehicle's Cab Floors in Rail Transit
摘要
Abstract
The problem of high noise level in the vehicle's cab of a railway track is studied. The finite element model of the cab's body is established considering structure and acoustic coupling effect. The finite element model of the floor structure of the cab is established and its sound insulation performance is simulated. The effectiveness of simulation of both finite element models is verified by comparing the simulation results with the measured values of the real specimens. Through the actual test, the optimized new floor structure is designed and is introduced to the established finite element models. It is concluded that the optimized design of the floor structure can significantly improve the noise inside the cab.关键词
