Tóm tắt

 This article presents survey contents of noise in the compartment of passenger vehicle with 29 seats which caused by vibrations of frame and body. The study used the FEM method to simulate spatial patterns of air volume inside the compartment of vehicle, used Ansys software to solve the problem. The load simulated in the model is the displacements of floor at the 16 bolts points assembled between the frame and the floor of the vehicle. When the engine running make the floor and frame and body of the vehicle shaking which will cause noise in the compartment of vehicle. Survey results have been noise at any location inside the compartment of vehicle with corresponding of sheet thickness different: 0.8
  1.0
