谐波定转子耦合为电机仿真中旋转子系统的互联提供了一种很有前途的方法。本文研究了类泊松问题砂浆方法框架下基于谐波耦合的离散化方案的稳定性。导出了一种通用准则，可以保证各种具体的离散化方法的相关稳定性条件，包括有限元方法和调和砂浆耦合等几何分析。通过数值试验验证了理论结果的有效性和精确性。
Harmonic stator-rotor coupling offers a promising approach for the interconnection of rotating subsystems in the simulation of electric machines. This paper studies the stability of discretization schemes based on harmonic coupling in the framework of mortar methods for Poisson-like problems. A general criterion is derived that allows to ensure the relevant inf-sup stability condition for a variety of specific discretization approaches, including finite-element methods and isogeometric analysis with harmonic mortar coupling. The validity and sharpness of the theoretical results is demonstrated by numerical tests.
