Description

technical field [0001] The invention relates to an electromagnetic testing device, in particular to an electromagnetic force testing device for a high-speed electromagnetic valve used in an automobile braking system. Background technique [0002] The high-speed solenoid valve is the key component to control the brake pressure in the automobile braking system. The switching function of the valve core is realized by the electromagnetic force generated by the solenoid valve coil. The strength of the electromagnetic force is an important index to measure the response speed of the high-speed solenoid valve, which is related to the quality and safety of the braking system and even the entire vehicle. The static test of the electromagnetic force of the solenoid valve can obtain the relationship curve between electromagnetic force and displacement, which provides a basis for the selection of solenoid valve materials; the dynamic test of the electromagnetic force of the solenoid valv...
