The Third Superharmonic Resonance Analysis of RLC Circuit with Sensor Electronic Components

摘要

Based on RLC series circuit of sensor electronic components with nonlinear capacitance research object, the first approximate solution of third superharmonic resonance of the nonlinear vibration system is obtained by means of the method of multiple scales for nonlinear oscillations. The third superharmonic resonance response curves of RLC series circuit have jump phenomenon and hysteresis phenomenon. With the increasing of resistance for all kinds of electronic components, the amplitude and resonant region of the primary resonance decrease. With the increasing of electromotive force (emf), the amplitude and resonant region of the primary resonance increase. The conclusion is provided a reference for design and manufacture of electronic components.
