Technical Field
The utility model relates to an electronic vibration test device technical field, in particular to electronic vibration test device is used in inspection of on-vehicle satellite positioning terminal.
Background
An electrodynamic vibration table is a converter that converts electrical energy into mechanical energy. The basic operating principle is based on the ampere's law that a current-carrying conductor is subjected to an electromagnetic force in a magnetic field. The electromagnetic force borne by the current-carrying conductor is in direct proportion to the current in the conductor, the effective length of the conductor in a magnetic field and the magnetic induction intensity of the magnetic field where the conductor is located, and the direction of the electromagnetic force is determined by the left-hand rule.
Because the electric vibration table works on the principle of electromagnetic conversion, the electric vibration table can only be operated in an air environment and cannot be completely exposed to water. Since water is a conductor in general, it can seriously affect the normal operation of electromagnetic conversion. If the electric table is to work under water, the electric table must be completely sealed, but the sealed electric table causes pressure difference between the inside and the outside, the pressure difference generates acting force on the table top, the table top is deviated inwards, the pressure difference is increased along with the increase of the water depth, and the inwards deviation of the table top is larger. The electric table must overcome the pressure difference to vibrate underwater, and the electric table cannot work when the pressure difference is large.
The method is usually adopted at present, compressed gas is filled in a sealing structure of an electric vibration table to counteract the acting force of the electric vibration table on a table top by pressure in deep water, so that a movable coil of the vibration table is positioned at the central position, and the up-and-down vibration of a vibration rod cannot be realized. When the working depth changes, the pressure of compressed gas in the sealing structure must be changed, only a compressed air injection opening is arranged on the sealing body, the inlet is connected with an air pipe and led to the water surface to change the gas pressure, and the deeper the working depth of the vibration table is, the greater the difficulty of realizing the method is.
