The Ship Struck by Lightning Indirect Effect Simulation and Data Analysis
Lightning strike simulation ships, ship body inside and outside surface current distribution of transient and frequency domain, the ship to hold various points transient and frequency domain the electric field and magnetic field distribution and ship to warehouse internal cables on the induction of transient impulse voltage and current and its frequency spectrum. Based on transmission line matrix, the indirect effect of lightning striking the ship is analyzed by CST (Computer Simulation Technology) according to GJB1389A and SAE-ARP5414 relative standards. In this paper, two kinds of lightning stroke paths are simulated by the high current injection. The simulation results show while the lightning stroke paths is not same, the transient magnetic field distribution and current distribution on the surface of the ship is different as well. Moreover, the research method can be used for further study on the protection of the lightning indirect effects and related research. The method can effectively simulate the lightning the lightning indirect effect of ships, for ship lightning protection design and relevant experiment provided the basis and method, has the important value of engineering application.
