Analysis of Primary Resonance of Nonlinear Vibration of Solenoid Switch Systems under Narrow-band Excitation
摘要
Abstract
The strong nonlinear vibration of the electric circuit and magnetic circuit coupled solenoid switch system under narrow-band excitation is investigated.The stochastic differential equation of the solenoid switch system subjected to narrow-band excitation is established.The frequency response equation of the system is obtained based on the modified multi-scale method.The stability of the primary resonance of the system is calculated.And the influence of the parameters of the system on the mean square value of the primary resonance of the system is analyzed.The results show that the mean square value of the primary resonance of the system reduces with the increasing of the damping coefficient,increases with the increasing of the excitation voltage amplitude,and reduces with the increasing of the resistance.The change of limit cycle of the system is small with the increasing of the intensity of the random disturbance.关键词
