The Calculation and Experiment Based on the Finite Difference Method for the High-Voltage Electrostatic Field of Melting Electron Beam Gun

Abstract:

Aiming at high voltage electrostatic field of melting electron beam gun system, taking 30 kv 60 kw melting electron beam gun for example, the structure of the electric field and boundary conditions was designed. And the mathematical model of the electric field was established. The method of numerical calculation was used to solve the mathematical model, and Matlab software was used to simulate the equipotential lines of the electric field. The electrolytic cell experiment was used to simulate high voltage electrostatic field distribution of the electron beam system. At the same time compared with the two different results, the reasons and the improved method were analyzed. For research and calculation high voltage electrostatic field of processing equipment such as electron beam welding, melting, etc, offers a more general analysis, design and calculation methods.
