Analysis of Acoustic Characteristics of a Car Cabin Using Computer-Aided Engineering

Abstract: A computer-aided engineering (CAE) model was developed to analyze the acoustic characteristics of a car cabin. Pro/Engineer Wildfire 4.0 was used to three-dimensionally represent the geometry of the cabin. The CAE, using COMSOL Multiphysics 4.2a, was performed to investigate the distribution of sound pressure fields at natural frequencies. The principle mode indices were (2, 1, 1), (2, 1, 1), (1, 1, 1), and (2, 2, 2), corresponding to the modal coefficients 1, 2, 3, and 4 and the natural frequencies of 179.691… Show more

“…Noise, vibration, and harshness (NVH) is usually used to evaluate the drivers' comfort of a vehicle [1,2]. With the increasing academic attention to the environment and the technical improvement of vibration and noise standards of construction machinery, the NVH performance of construction machinery has been adopted by major manufacturers in recent years.…”
