建立非线性振动输送机力学模型,应用非线性振动理论对系统进行动力学分析,将该分析用于现场,得出主振、隔振弹簧分别为变、常刚度时,在非线性近共振长距离振动输送机的工作过程中,空载或重载工况下均为双质体异向振动之结论。 The dynamic model of nonlinear vibration conveyor is established. The nonlinear vibration theory is used to analyze the system dynamics. The analysis is applied to the field. The results show that when the main vibration and vibration isolation springs are respectively variable and constant stiffness, Vibration conveyor from the work process, no-load or heavy load conditions are the double body of heterodyne vibration conclusion.
