摘  要:
In this paper, a study on the calculation of acoustic radiation caused by a random vibrating body was carried out, based on the statistical boundary point method (SBPM) and the SBPM was described in detail. An experiment on the external acoustic radiation from a simulated random vibrating axial box in a lathe tool was performed in a semi anechoic chamber. The comparison between the predicted results by the SBPM and the measured ones revealed that the SBPM was an effective method for the calculation of acoustic radiation problem of a random vibrating body.
