船舶柴油机排气消声器性能的边界元法分析

The research on the analysis of the property of shipping diesel engine exhaust silence

应用边界元法对船舶柴油机消声器的性能进行了数值计算 ,并通过实验证明计算结果是正确的 ,这为消声器的设计和管理提供了一种有效的方法 .

On the basis of introducing the theory of the boundary element method(BEM),the mathematical model is established and the computer program is compiled by using number integral calculates the parameters of silencer.In order to testify whether the calculation method and computer program is right or not,compare the testing data with the calculating data.These works can provide an applied methods for structure design of the silencer.
