In view of the electromagnetic force, furthermore, several parameters related to the solenoid valve performance are considered and their effects on solenoid valve are analyzed and discussed. Finally, the optimized parameters are proposed for the analyzed solenoid valve and proved by theoretical equations. The studied approach can be extended to any other field related to the electromagnetic device design.

Each part of the model in ADAMS was set up. Simulation analysis on the working process of the mechanism was achieved. The structure optimization parameters of the mechanism were obtained. The result proves that when the vertical location of the upper endpoint of lid were increased the horizontal displacement of the lower endpoint of lid reduced. When the locations of revolute joint of lower rocker and link, the horizontal location of revolute joint of lower rocker and lid, the opening force acting on the lower endpoint of lid were increased the horizontal displacement of the lower endpoint of lid added. The sensitivities of the horizontal displacement of the lower endpoint of lid on the initial values of the locations of revolute joint of lower rocker and link, the horizontal location of revolute joint of lower rocker and lid, the horizontal location of revolute joint of lower rocker and frame are greater. The sensitivities of the horizontal displacement of the lower endpoint of lid on the initial values of the vertical location of revolute joint of upper rocker and link, the vertical location of the upper endpoint of lid, the opening force acting on the lower endpoint of lid are smaller.
