本文提出了一种基于on /OFF法的同步电机拓扑优化方法，以获得实际形状。使用进化算法（如遗传算法）的TO经常产生复杂的形状，这些形状在工程意义上是不可能产生的。在之前提出的方法中，开/关方法需要点阵网格。这导致曲面的表达能力差，限制了网格的生成。为了解决这一问题，对该算法进行了扩展，使其适用于非结构化网格。将该方法应用于同步电机的形状优化，优化结果表明，得到了可行的形状，并改善了电机的转矩性能。
A topology optimization (TO) of synchronous motors based on the ON/OFF method to obtain practical shapes is presented in this paper. The TO using evolutionary algorithms such as genetic algorithm often yields complex shapes that are impossible to produce in an engineering sense. In the previously proposed method, lattice meshes were required for the ON/OFF method. This results in poor ability of expression for curved surfaces and restriction of mesh generation. To solve this problem, the algorithm is extended to adapt to unstructured meshes. The present method is applied to a shape optimization of synchronous motors, and optimization results show that feasible shapes are obtained and torque property is improved.
