用于预定义外部磁场的拓扑优化和3D打印Polymer粘结永磁体
Topology Optimized and 3D Printed Polymer Bonded Permanent Magnets for a Predefined External Field
摘要：
拓扑优化为设计具有特定外场特性的永磁系统提供了很好的机会。使用最终用户3D打印机的聚合物粘结磁体的增材制造可用于制造具有先前难以或不可能制造的结构的永磁体。本工作将这两种强有力的方法结合起来，设计和制造具有特定性能的永磁系统。该拓扑优化框架简单、快速、准确。它也可以用于永磁体的逆向工程，以便从磁场测量中找到拓扑结构。此外，提出了在磁体上方产生线性外部场的磁系统。在体积约束的情况下，可以在不损失性能的情况下最小化磁性材料的量。印刷系统的模拟和测量显示出非常好的一致性。
英文摘要：
Topology optimization offers great opportunities to design permanent magnetic systems that have specific external field characteristics. Additive manufacturing of polymer bonded magnets with an end-user 3D printer can be used to manufacture permanent magnets with structures that have been difficult or impossible to manufacture previously. This work combines these two powerful methods to design and manufacture permanent magnetic system with specific properties. The topology optimization framework is simple, fast, and accurate. It can be also used for reverse engineering of permanent magnets in order to find the topology from field measurements. Furthermore, a magnetic system that generate a linear external field above the magnet is presented. With a volume constraint the amount of magnetic material can be minimized without losing performance. Simulations and measurements of the printed system show a very good agreement.
