用传递矩阵法对汽车排气消声器进行性能模拟。编写了消声性能模拟软件,用该软件对消声器进行性能模拟,其模拟结果与实验结果吻合较好。并对消声器进行了优化设计,优化后消声器消声效果明显提高。
Using transfer matrix method to simulate the performance of automobile exhaust muffler. The anechoic performance simulation software was written and the performance of the muffler was simulated by the software. The simulation results agree well with the experimental results. And the muffler was optimized design, the muffler muffler optimization effect was significantly improved.
