Technical Field

[0001] The utility model relates to the field of experimental equipment, in particular to automatic electromagnetic impact vibration experimental equipment. Background Art

[0002] The electromagnetic coil, also called the excitation coil, is a component that generates magnetism to drive the charged coil to move.

Due to the deviation in the processing of the electromagnetic coils and the unevenness of the coil material, there is a large error between the calculated electromagnetic impact force and the actual electromagnetic impact force. This problem is urgently needed. Utility Model Content

[0042] The working principle of the utility model is as follows: before starting to use an automatic electromagnetic shock vibration test equipment, the electromagnetic coil is sleeved on the outside of the automatic electromagnetic shock vibration test equipment. During this process, the automatic electromagnetic shock vibration test equipment is located in the middle of the electromagnetic coil and is fixedly connected to the outside of the electromagnetic coil through a connecting plate. At this time, the mounting seat 6 is located at the limit position of the guide groove 2; when starting to use an automatic electromagnetic shock vibration test equipment: the external control system energizes the electromagnet in the first piece 12, so that the electromagnet generates an electromagnetic force, which is opposite to the magnetism on the support member 10, thereby separating the moving member 11 from the support member 10. During this process, the moving member 11 is located between the upper sensor 8 and the lower sensor 9, and the upper sensor 8 and the lower sensor 9 cannot detect the signal of the moving member 11. At this time, the upper sensor 8 and the lower sensor 9 transmit the detection result signal to the external control system, and the external control system starts to energize the moving member 11. During this process, the moving member A closed loop is formed in 11, which is acted upon by the electromagnetic force of the electromagnetic coil, thereby driving the movable member 11 and the mounting seat 6 to make a linear motion in the guide groove 2. During this process, the mounting seat 6 stops after reaching the limit position, and the external control system stops supplying power to the movable member 11. Then the external control system supplies a reverse current to the movable member 11 again to make the mounting seat 6 move in the reverse direction in the guide groove 2 until the mounting seat 6 reaches another limit position and stops. Then the external control system stops supplying power to the movable member 11 again, and then supplies the same reverse current to the movable member 11 again, repeating the above steps to ensure that the movable member 11 and the mounting seat 6 make multiple reciprocating motions in the guide groove 2. During this process, the detection head 5 and the grating ruler 4 cooperate with each other to detect the change in the position of the movable member 11, and transmit the detection signal to the external control system. The external control system determines the acceleration, speed and other parameters of the movable member 11 through the signal transmitted by the detection head 5, thereby obtaining the magnitude of the electromagnetic impact force of the coil on the movable member 11.
