| 摘 要： | 边界元法(BEM,Boundary Element Method)是声场分析的一种有效方法,对于开口结构的声场分析,可采用内外声场的直接边界元耦合法或多域的间接边界元方法。本文分析了求解不封闭声腔的直接边界元法与间接边界元法,总结了两种方法的基本理论及求解过程,并以具体开门的驾驶室声场分析为实例对两种方法进行了分析比较。

| Abstract: | BEM was a method which is used for acoustic field analysis.For unclosed acoustic enclosure,there are two methods,indirect BEM and direct BEM coupling.This paper summarized the basic theory and solving process of the two methods,and analyzed the acoustic field analysis of the cabin with open door in order to compare the two methods. |
