【摘要】 针对有限元分析软件ANSYS在进行大规模仿真时存在的重复建模缺点,以VC为平台,对ANSYS参数化设计语言(ANSYS parametric design language,APDL)进行二次开发,建立可视化操作界面,后台调用ANSYS,自动完成对铁心电抗器的参数化建模与有限元仿真分析,达到有效缩短产品设计周期的目的。然后通过磁路法以及能量摄动法两种求解电感的方法比对,验证了该系统的准确性及可用性。最后提出了一种对有限元仿真进行批量处理的方法,并据此进行了共计132次三维非线性瞬态磁场仿真,探究了不同含量,次数以及相位的谐波与基波叠加后的非正弦激励对铁心电抗器磁场造成的影响,对掌握谐波作用下铁心电抗器的磁场分布规律具有参考价值。更多还原

【Abstract】 In view of the repetitive modeling shortcoming of the finite element analysis software ANSYS exisited in large-scale simulation,the VC is taken as as a platform to perform the secondary development of ANSYS parametric design language(APDL),set up a visual operation interface,call ANSYS in the background to complete automatically the parametric modeling and finite element simulation analysis of the iron core reactor with purpose of effectively shortening design period of product. Then,both accuracy and applicability of the system are verified by comparison of such two inductive methods as magnetic circuit method and energy perturbation method. Finally,a kind of method for batch processing of finite element simulation is proposed and,on this basis,a total of 132 times of three-dimensional nonlinear transient magnetic field simulations are performed and the influence of non-sinusoidal excitation after superposition of harmonics and fundmental waves containing different contents,numbers and phase on the magnetic filed of the core reactor,which provides reference for mastering the distribution law of magnetic field of core reactorunder the action of harmonics.更多还原
