摘要
推导出两端简支排气管气固耦合系统振动方程,研究排气管气固耦合系统的振动特性,并通过实验分析排气管气固耦合系统在特殊环境下的频率,为改善排气管的排气消声性能积累经验。
The vibration equations for gas-structure coupling system of exhaust pipeline with two simply supported ends are derived for studying its vibration characteristics. The experimental analysis on the vibration frequency of gas-structure coupling system of exhaust pipeline under special circumstances provides helpful data for improving the silencing performance of exhaust pipeline.
