Abstract

As a new type of braking method, the eddy current brake (ECB) is nowadays widely applied in life and military. The ECB can generate the strong resistance by the magnetic field, and obtaining the accurate magnetic induction distribution is essential in the ECB modeling. This paper proposes an analytical model of a cylinder ECB used in the artillery that operates under the intense impact load. This model takes the axial edge effects into consideration in both static and dynamic conditions. Firstly, this paper introduces the structure and working principle of this ECB. Secondly, a multilayer theory with virtual region is proposed to calculate the magnetic induction distribution considering the end effect. Thirdly, Finite Element Method (FEM) model is established to describe the spatial variation of the magnetic field in different conditions. Finally, the analytical model is compared with the FEM model to prove its validity and predict the working characteristic of the ECB under the intense impact load, the max recoil displacement and speed range both meet design and work requirements.

考虑末端效应的永磁圆柱涡流制动器快速建模方法

作为一种新型制动方法，电涡流制动器（ECB）如今已广泛应用于生活和军事领域。电涡流制动器在磁场的作用下会产生强大的阻力，因此获得精确的磁感应分布对于电涡流制动器的建模至关重要。本文提出了火炮中使用的圆筒形 ECB 的分析模型，该圆筒形 ECB 在强烈的冲击载荷下工作。该模型考虑了静态和动态条件下的轴向边缘效应。首先，本文介绍了这种 ECB 的结构和工作原理。其次，本文提出了一种具有虚拟区域的多层理论，用于计算考虑到端部效应的磁感应分布。第三，建立有限元法（FEM）模型来描述不同条件下磁场的空间变化。最后，将分析模型与有限元模型进行比较，以证明其有效性，并预测 ECB 在强冲击载荷下的工作特性，其最大反冲位移和速度范围均符合设计和工作要求。
