摘要

在谐波砂浆法中使用三角多项式作为拉格朗日乘子，可以有效而优雅地处理电机定转子耦合仿真中的相对运动。从能量分析的角度推导了扭矩计算的显式公式，并讨论了谐波砂浆有限元和等几何分析离散化的实现方法。通过数值试验验证了理论结果，并证明了调和砂浆法在评估转矩波纹方面的潜力。

On torque computation in electric machine simulation by harmonic mortar methods

The use of trigonometric polynomials as Lagrange multipliers in the harmonic mortar method enables an efficient and elegant treatment of relative motion in the stator-rotor coupling of electric machine simulation. Explicit formulas for the torque computation are derived by energetic considerations, and their realization by harmonic mortar finite element and isogeometric analysis discretizations is discussed. Numerical tests are presented to illustrate the theoretical results and demonstrate the potential of harmonic mortar methods for the evaluation of torque ripples.
