【摘要】 针对目前电动机设计课程实验教学手段单一的问题,基于Jmag软件,以鼠笼式异步电动机设计过程中的电磁噪声分析为例,给出电动机仿真建模及电磁噪声分析过程的实例,阐述了可视化有限元仿真技术在电动机设计实验教学中的积极作用。实践结果表明,基于可视化有限元分析软件的仿真实验教学直观形象,有利于学生深入理解电动机运行过程中的电磁振动及噪声问题,同时又能提高学生的综合实践能力,取得了良好的教学效果。更多还原

【Abstract】 Aiming at the problem of single means in experimental teaching of the machinery design course, by using JMAG software and taking the electromagnetic vibroacoustic analysis of squirrel-cage asynchronous motor as an example, this paper illustrates the finite element analysis process for the machine modeling and electromagnetic vibroacoustic analysis, which indicates the positive role of finite element simulation technology in experimental teaching of machinery design. The practical results show that the visual simulation based on the finite element analysis software is beneficial to the students in deeply understanding the electromagnetic vibroacoustic analysis. Also the comprehensive practical ability of students can be improved, thus, it leads to good teaching results.更多还原
