Abstract: Through introducing the nonlinear restoring couple moment in the ray vibrator oscilloscope system,a nonlinear vibration equation is established and conditions that can bring out the primary resonance of the vibrator system are analyzed.The method of multiple scales is employed to obtain the approximate solution for the primary resonance of the vibrator system and numerical calculation is made.The authors of this paper discuss the influence of the magnetic induction intensity,current signal strength,the damping on the vibration system,which shows that the increase of the magnetic induction intensity or the current signal strength of the vibration system will lead to the rise in the primary resonance amplitude and primary resonance region of the system and that the increase of the damping of the vibration system will lead to the decrease of the primary resonance amplitude and primary resonance region of the system and vice versa.
