摘要：
This paper describes an investigation on the sound radiation from forced vibration of rectangular orthotropic plates under moving loads. The vibrations of a rectangular orthotropic thin plate with general boundary conditions traversed by moving loads are first solved. Based on the Rayleigh integral and the dynamic response of the plate, the acoustic pressure distributions around the plate are obtained in the time domain. The effects of light and heavy moving loads are separately studied. Simplified methods for calculation of the acoustic pressure distributions in far field are developed. The effects of moving mass, damping coefficient, boundary conditions and moving speed on the dynamic responses of the plate and the acoustic pressure distributions are investigated.
