一款3D打印发动机教具设计

Design of a 3D printing engine teaching aid

针对教师上《发动机构造与检修》这门课程教学时,存在理论教学效果不佳,学生学习兴趣不浓的现象,设计了一款3D打印发动机教具来改善教学,该教具可完美展示发动机的内部构造及工作原理,具有体积小,质量轻,方便携带等诸多优点,解决了教师不能将沉重发动机带入课堂的难题,同时提高了学生的学习兴趣。实践效果证明,采用3D打印发动机教具教学可明显提高该门课程学生的理论和实践水平,具有很大的推广价值。

In view of the phenomenon that the theoretical teaching eff ect is not good and the students'interest in learning is not strong,a 3D printing engine teaching aid is designed to improve the teaching.The teaching aid can perfectly display the internal structure and working principle of the engine.It has many advantages such as small size,light weight,convenient carrying,etc.,which solves the problem that teachers can't solve,that is,the heavy engine cannot be carried into the classroom problems,while improving students'interest in learning.The practice results show that the use of 3D printing engine teaching aids can signifi cantly improve the theoretical and practical level of students in this course,and has great promotion value.
