摘要
本文采用三维坐标将声压作为未知参数,描述了抗性消声器三维声学边界元模型的建立及其在492Q型汽油机排气消声器设计中的应用.计算的插入损失与实测结果十分一致.研究结果表明,三维声学边界元模型是抗性结构消声器声场分析的有效方法并具有较高精度.
In this paper, sound pressure being taken as an unknown variable, a three-dimensional acoustic boundary element model of reactive mufflers is established and its application to exhaust muffler design on 492Q type gasoline engines is also described. The computed inserting loss has a good consistency with the experimental result. The research shows that the three-dimensional acoustic boundary clement model is an efficient and highly accurate method of sound field analysis of reactive mufflers.
