Analysis and Optimization of Electromagnetic Force Horizontal Characteristics of Pilot-operated Proportional Solenoid Valve
As the core component of the suspension system,the damping adjustable shock absorber is very important to the driving smoothness of the car,and the pilot-operated proportional solenoid valve,as an important component in the shock absorber,plays a key role in the performance of the shock absorber.The structure and working principle of the solenoid valve were introduced,the simulation model of the solenoid was established by Maxwell 2D finite element simulation software,the electromagnetic force-displacement horizontal characteristics under static condition were simulated and calculated,and the structural parameters such as the inclination angle,guide sleeve thickness,armature length,armature width and other structural parameters of the solenoid magnetic isolation ring were adjusted and analyzed according to the simulation results,and the accuracy of the simulation model was verified by the electromagnetic force horizontal characteristic test.The orthogonal experimental method was introduced to co-optimize the parameters,and the standard deviation was used to measure the electromagnetic force level characteristics.The standard deviation of the optimized product was 0.635888,and the optimization effect was increased by 7.98％.It lays a foundation for the simulation and analysis of the mechanical-electrical-hydraulic-magnetic coupling of the valve body.
