| 摘 要： | 作为一种新兴的实验手段,虚拟实验已成为高校实验教学的重要组成部分。在开发电动机拖动系统虚拟实验时,针对Multisim软件存在的不足和教学实验要求,搭建了电动机模型和多种负载模型。详细论述了基于Multisim的电动机拖动系统仿真模型的设计方法与封装步骤,针对Multisim仿真不收敛的情况,给出了相应的解决方法,列举了该仿真模型在虚拟实验教学中的应用案例,总结了在电动机及拖动基础课程中使用上述电动机拖动系统虚拟仿真模型的特色与优势。教学实践表明,基于该模型的虚拟实验可与实验室实验互为补充,互相促进,帮助学生提升实验技能,开阔学生视野,实现知识的迁移与融合。

| Abstract: | Virtual experiment,as a burgeoning experimental technology,has become one of the key elements of experiment teaching system in universities.SPICE models of motor drives are developed to meet the requirements of teaching and to overcome the shortcomings of Multisim software.The processes of developing the models of different kinds of motors and loads are detailed presented.The methods for convergence during simulation are described step by step.The examples for utilizing the models are also illustrated and then the characteristic and advantage are summarized.The experiment teachings show that the virtual experiments based on the above models are complementary and mutually promoting.The virtual experiments acquaint the students with the skills and widen students’visions. |
