瞬态运动电磁问题的时步有限元方法研究
Research on the Time Stepping Element Method for Solving the Transient Motion Electromagnetic Problems
摘要
Abstract
Based on the method of dealing with the motion electromagnetic problems, a summary of existing research methods was done. By introducing the concept from the fluid dynamics, the ways were divided into the Eulerian description and the Lagrangian description, and the relationship between two parts was derived. Then the eddy current field control equations with the descriptions were described, respectively. Then, we pointed out the impact of speed item to the eddy current, and we verified that the moving rotor's stiffness matrix was not changed. For both of the Eulerian description and Lagrangian description had its own shortcomings, in this paper, we used a way by combining the Eulerian and Lagrangian description with time-stepping finite element method to deal with the moving conductor eddy current problems. A three-phase asynchronous induction motor was proposed to analyze the no-load startup process. The result of stator phase current with time, electromagnetic torque with time, and motor speed with time, well verified the validity of the method in dealing with such movement关键词
