摘要
根据有限元方法(FEM)求解鱼雷近炸引信对目标舰反射的磁场信号。通过建立雷目交汇时的三维数学模型,加载边界条件进行三维有限元数值分析,然后根据经典电磁波传播、反射理论和通过特性经验公式进行回波信号仿真。研究结果表明文中方法产生的结果与实际测量值基本吻合。
The target echo of proximity fuze for torpedo was discussed by using FEM（finite element method） in this paper. The 3D mathematic model for intersecting of torpedo and ship was established. Based on the simulation by FEM numerical value analysis was conducted in boundary conditions. Then according to the classical electromagnetic wave theory and experience formula of overpass characteristic, the echo was simulated. Simulation results indicate that the target echo and overpass characteristic got by simulationare is almost consistent with those got from test.
