摘要
在阐述了体积合成算法基本原理的基础上,对其进行改进,使其适用于存在平均流的消声器声学特性的预测。使用改进后的算法对一些不同结构类型消声器的传递损失进行预测,并通过与有关文献和实验数据的对比进行验证。最后以一个实例讨论了平均流对消声器声学性能的影响。
On the base of a description on its basic principle, the volume synthesis algorithm （VSA） is im- proved to adapt to the prediction of the acoustic characteristics of muffler with mean flow. The improved VSA is then used to predict the acoustic characteristics of a few mufflers with different types of structure, and the results are veri- fied by comparing them with data in related literatures and test data. Finally the effects of mean flow on the acoustic performance of muffler are discussed with a real example.
