摘要
基于管道声学理论,利用AVL公司的Boost软件建立排气消声器模型,进行某轿车的排气消声器改进设计.实验证明,这种设计方法能够充分考虑发动机排气气流对消声性能的影响,并可以在消声器设计过程中兼顾发动机的综合性能和消声器的消声性能,是排气消声器设计的理想方法.
Based on the theory of flow duct aoustics,simulating model of a muffler is established by using the AVL BOOST,and improved design of the exhaust muffler of a car is implemented.The test results testify that the simulation method is able to consider the unsteady flow of the gas from the exhaust muffler and give attention to both the comprehensive performance of engine and muffler.It is an ideal method to design muffler.
