摘要
将提出的统计边界点法应用于随机振动结构声辐射问题的分析计算 ,通过模拟车床主轴箱随机辐射声场的统计边界点法分析与实验测试结果的对比 。
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.
