摘要

为明确电抗器声场分布特性及计算方法

在振动和声压测量的基础上

采用Soundplan噪声软件和BEM数值法对电抗器声场进行了重构

并与实测值进行了对比分析

建立了相对准确的电抗器声场计算方法。结果表明

电抗器本体表面振动因结构差异具有不对称性

其声场分布复杂

干涉现象明显;Soundplan噪声预测软件无法考虑声波干涉

计算结果与实测声场差别较大

而BEM数值法能较好仿真电抗器随距离增加而波浪衰减的过程

且能重构声场中任意点的声压

并计算声功率级;防火墙对电抗器声波干涉影响较大

地面反射影响相对较小

对防火墙进行吸声处理

可在一定程度上控制电抗器声波干涉。

Abstract

To understand the sound field characteristics and calculation method of a reactor

the noise prediction software Soundplan and the BEM numerical method are used to reconstruct the sound field of the reactor

and the calculated results are compared analytically with the vibration and sound pressure measurements. As a result

a relatively accurate method for calculating the sound field of the reactor is obtained. It is shown that: 1)the surface vibration of the reactor is asymmetric due to the structural difference

the sound field distribution is complicated

and the interference phenomenon is obvious;2)Soundplan cannot consider the acoustic interference

so the calculated results are quite different from the measured data;3)the BEM numerical method can better simulate the attenuation process of the reactor with the distance increasing

and it can reconstruct sound pressure at any point in the sound field and calculate the sound power level;4)the firewall has a great influence on the noise interference of the reactor

while the ground reflection effect is relatively small;and 5)the acoustic treatment of the firewall can control the acoustic interference of the reactor to a certain extent.
