摘　　要：根据悬挂链曝气装置结构和悬挂链摆动过程,建立了系统的二维动力学模型,并以某参数为实例进行了数值求解,给出了曝气器、供气管位移随时间变化关系与相图。结果表明,悬挂链移动曝气具有明显的非线性性质,同时揭示出非线性性质与悬挂链曝气装置随机摆动的内在联系。According to the characteristics of equipment structure and oscillation process for suspended chain aeration, a two-dimension dynamic model of suspended chain aeration is established, and the phase diagram and displacement-time graph about suspended chain aerator and air supply pipe are obtained by the numerical solution for a set of given parameters. The results indicate that there exists serious nonlinear property in suspended chain moving aeration that can be extended to explain the stochastic oscillation phenomena of suspended chain aerating equipment.
