机械原理课程设计是机械原理教学的一个重要的实践环节。以往我们机械原理课程设计存在着很多不足。主要问题是学生完成课程设计后，在后续课程的学习和实践中，不能正确地选用和设计机械，特别是创造性设计新机械的能力与分析解决实际工作问题的能力、动手能力和适应能力还显 Mechanical Theory Course design is an important part of the teaching of mechanical principles. In the past we have a lot of mechanical design theory deficiencies. The main problem is that after completing the course design, students can not correctly select and design machinery in the follow-up course study and practice, especially the ability to creatively design new machinery and the ability to analyze and solve practical work problems.
