Paper Title:
Research on Simulation Platform Architecture for Noise Reduction of Electric Locomotive Wheel
  Abstract

Wheel/rail rolling noise is the main source of noise from railway operations, it is at least as important as aerodynamic noise. In this paper, the makeup of unit modules of CAE(Computer Aided Engineering) simulation platform for of railway passenger car and its function frame are given. Based on finite element method, boundary element method, the structural model, interior acoustic cavity and acoustics model of electric locomotive wheel were analyzed by Nastran and Sysnoise software. This paper is imposed sinusoidal excitation on the wheel, and then the laying of the viscoelastic layer and optimization of damping-wheel, obtain the wheel’s structure of the vibration noise radiation.The analysis result shows that the laying of the viscoelastic layer can reduce wheels radiation noise, and the noise can be reduced from 0.27 to 8.62 dB.Practical application indicated this simulation platform can supply effective technology support for the development of product.
