1 问题的提出 高等学校工科各专业普遍要讲授机械零件课程,它是一门实践性较强的技术基础课。为了贯彻“精减教学内容,改进教学方法,加强实践环节”的教学改革精神,根据教学大纲的内容,建立一个机械零件教学陈列室,帮助学生学习和掌握本课程的知识,开阔学生的视野是十分必要的。这就要求陈列室的展品中具有各种类型的通用机械零件、部件,并且还要具有各种典型结构和典型失效形式。这些机械零部件,特别是失效的
1 The question raised Engineering colleges and universities generally teach the various mechanical parts course, it is a practical basic course of technology. In order to carry out the teaching reform spirit of “reducing teaching content, improving teaching methods and strengthening practical links”, a mechanical display room is set up according to the contents of the syllabus to help students learn and master the knowledge of this course and broaden their horizons Very necessary This requires all types of general mechanical parts and components to be displayed in the showroom, as well as various typical configurations and typical failure modes. These mechanical parts, especially those that fail
