摘　　要：本文建立了一种分析排气谐振系统特性的简化力学模型,求出了谐振箱内压力波动值的解析表达式,并将其应用于工程实际,解决了二冲程汽油机最大扭矩点的定点问题。实验表明:这种简化模型和由此导出的计算公式可以满足工程设计的要求。A simplified mechanical model which can be used to analyse the characteristics of exhaust resonance system is established in this paper. An analytical solution of pressure wave in resonant box is obtained by means of the model. It＇s used for engineering, and the maximum torque point of two-stroke gasoline engine can be fixed by it. The experiment has proved that formulas derived from the model can meet the needs of engineering practice.
