摘　　要：以某款排气消声器优化设计为例,介绍了如何运用GT-POWER进行噪声优化的过程。在优化初期,可先测试出未达标频率段,并通过GT-POWER模拟分析消声器的传递损失,对比未达标频率段与消声器的传递损失,即可针对性地修改消声器内部结构,最后通过实车测试,验证排气噪声是否达标。The optimization design of exhaust muffler by GT-POWER is described. At first, frequency section that doesn＇t reach the standard can be tested and muffler transmission loss is got. The muffler structure can be modified according to the contrast between that frequency section and transmission loss of the muffler. Last by real test, muffler acoustic effect in vehicle is testified to see if it reaches the standard.
