In order to deeply understand the influence of driving position of vibrating flip-flow screen on motion characteristic of main and floating screen frame, mechanical model and vibration differential equation of the vibrating flip-flow screen were established with consideration of the effect of damping.The formulas of amplitude and phase of main and floating screen frame were derived using complex number method under different forms, and the click here method of determining phase through quadrant was also proposed based on practical problems in Engineering.In addition, the feasibility of vibrating flip-flow screen driven by floating screen frame was also analyzed theoretically.The motion characteristics of main and floating screen frame of vibrating flip-flow screen driven by main screen frame and driven by floating screen frame were compared under the condition that only position of vibration exciter was changed while the first natural frequency and the second natural frequency here remain unchanged.Eventually, characteristics of the floating driving flip-flow screen were obtained, such as, low resonance frequency, wide frequency modulation area and large amplitude of main and floating screen frame.
