摘　　要：应用GT-Power软件及其Muffler模块建立了简单扩张式抗性消声器模型,在模型的基础上对抗性消声器的结构和消声性能进行了模拟仿真分析,明确了消声器的扩张比、偏置、插入管、穿孔管、穿孔板等结构因素对抗性消声器消声性能的影响关系,有利于消声器的优化设计,便于消声器性能的进一步分析。GT-Power software and its Muffler module were applied to establish a simple expansive and reactive muffler model.Based on the model,structure and anechoic performance of the reactive muffler was analyzed through simulation.The effect of structural factors such as expansive proportion,offset,inserted pipe,perforate pipe,perforate baffle and so on to the anechoic performance of the reactive muffler was nailed down.This was propitious to the optimization design of the muffler and convenient for the further analysis to the anechoic performance.
