Numerical simulation and experiment validation on lightning-induced effects of a special vehicle

In recent years, with the development of the system integration technology, the outside integrative special vehicles, such as big oil tank, trucks loading with dangerous goods and so on, are becoming more and more important. When the vehicle is under way, it will inevitably encounter the nature environment, including lightning. If the lightning strikes directly or very close to the vehicle, the lightning-induced effects will be very destructive. Therefore, for a better understanding of the lightning-induced effects produced on the special vehicle by the lightning strike, the research on lightning-induced effects of a special vehicle for aerospace system transportation was proposed. In the paper, a numerical simulation model for the special vehicle is established, the lightning-induced effects are analyzed successfully by using tramsmission-line matrix (TLM) algorithm, and the experiment validation example is also implemented. By comparing the numerical simulation with the actual experiment results, the correctness trend of the numerical simulation is validated and a mass of invaluable research data is obtained, which has a deep significance on the lightning research in our country.
