机械设计课程中“疲劳设计”部分的教学方法探讨

Discussion on Teaching Method for " Fatigue Design" in the Course of Mechanical Design

机械设计课程中"疲劳设计"部分的教学一直是教学的重点和难点之一。笔者根据教学实践,从疲劳设计部分内容的教学逻辑构建、材料的疲劳特性曲线教学方法、零件的疲劳曲线及安全系数计算的教学方法三个方面,系统分析了疲劳设计这部分内容的教学思路、教学衔接过程及每一部分的注意事项,并详细阐述了在上述每一部分内容的教学过程中的注意事项。

The teaching of fatigue design in the course of mechanical design is always the important and difficult point in class teaching.According to years of teaching experience,we have analyzed the concept of teaching method systematically from three aspects：the teaching logics of fatigue design,the teaching method of material fatigue curves and element fatigue curves for safety factor calculation.Notes and attentions are mentioned in every step and in detail in the course of teaching.
