摘要
针对船模制作过程中舰用薄钢板采购费时、价格昂贵等问题,研究了一种被称为"磁导率-厚度积成比例"的方法。仿真分析结果表明,当两种薄壳体材料的磁导率-厚度积相等时,它们制作出的船模的感应磁场是相等的,因而这两种薄壳体材料可相互替代,且替代后不会改变壳体内部铁磁设备的磁场分布,不会改变消磁绕组通电磁场及绕组通电使舰艇铁磁物质磁化后所产生的磁场分布。这些结论充分说明,在磁性船模制作中采用普通薄钢板来等效替代舰用薄钢板是完全可行的,这将极大地提高磁性船模的制作效率,降低制作成本。
In the process of making the magnetic mock-up, the purchase of the thin steel plate used by the ship is time-consuming and expensive. A method called ＂the scaled permeability-thickness product＂ is studied. The results of simulation analysis show that when the permeability-thickness products of the two thin shell materials are equal, the magnetic field of the mock-up they made is equal, therefore, the two thin shell materials can be replaced by each other, and the substitution will not change the magnetic field distribution of the ferromagnetic equipment inside the shell. These conclusions fully indicate that it is completely feasible to replace the thin steel plate used in the ship by using the ordinary thin steel plate in the making of the magnetic mock-up. This will greatly improve the production efficiency of the magnetic mock-up and reduce the production cost.
