Simulation study on influence factor of electromagnetic deflection of projectile between polar plates
摘要
Abstract
[Objectives] Deflecting an incoming projectile using electromagnetic force on the projectile body between polar plates is a creative protection method for weapons and equipment. In order to study the adaptability of the wire current theory and the influence factor of the deflecting electromagnetic force, [Methods] the wire current theory of electromagnetic force is established and a simplified model and 3D model simulated on the basis of the finite element method. Using changing simulation parameters and a fitting method,the electromagnetic force variation is then studied under the influence of such factors as the geometric parameters of the plates,impact location and penetration angle of projectile.[Results] The obtained results are as follows:the deflecting electromagnetic force in the 3D simulation is only 1/7 that of the wire current model, so the wire current theory is not suitable for the 3D design of passive electromagnetic armor;the electromagnetic force decreases with the width of the plates in accordance with the power function law;the lateral deflecting electromagnetic force has a quadratic function with the impact location in the transverse and lateral directions;and the penetration angle has little impact on the lateral deflecting electromagnetic force.[Conclusions] The results of this paper can provide a foundation for the mechanism experiments,conceptual design and ship application of passive electromagnetic armor.关键词
