【Abstract】 Based on the creation of FEA model for ABS solenoid valve,we computed the magnetic force acting on the valve core and the self inductance of valve winding with different work air gap and different current.Through the core motion equation and the winding circuit equation,the magnetizing time and the release time are computed,and the response characteristics of valve core and winding current are analyzed by simulation.The results show that this analysis method can assure high precision and shorten the analysis period.更多还原
