【 摘 要 】

In order to verify that the non-uniform diameter of the metal jet can be deformed to a smaller diameter difference after the action of the electromagnetic field, a convenient and feasible test method is proposed. Mercury liquid metal was used as the test medium and a thermometer was used as the test equipment. A high-speed camera was used to record the deformation of the liquid metal, and the deformation of the liquid metal by the electromagnetic field was visually shown. The test results show that the liquid metal mercury is rapidly deformed by the electromagnetic field. The greater the magnetic induction intensity is, the stronger the deformation is. The greater the pulse discharge current is, the more obvious the mercury deformation is. The deformation measurement result conforms to the basic theory of the electromagnetic field. This method can be used to measure the electromagnetic field. The rapid deformation and flow under the effect provide a reference for the study of the deformation measurement of the electromagnetic enhanced armor technology and the electromagnetic constrained forming technology.
