Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0031] Such as figure 1 As shown, a solenoid valve performance analysis method based on multi-physics field optimization includes the following steps:

[0032] S1. Establish a dynamic electromagnetic differential equation: the electric field and magnetic field of the solenoid valve are coupled through the flux linkage. When the solenoid valve coil is energized, a magnetic field is generated around the solenoid valve coil due to electromagnetic induction. The magnetic field acts on the valve core, causing the valve core to move, thus changing The magnetic resistance at the air gap of the spool changes the magnetic flux accordingly. According to Kirchhoff’s voltage law, the driving voltage of the solenoid valve can be divided into a resistance component and an inductance c...
