摘要
直梁纯弯曲实验简易加载装置在小规模院校中得到广泛地推广,但该装置使用若干年后会出现比较大的误差,影响教学效果。分析了装置的优缺点,阐明装置改进的理论依据,介绍改进过程。改进后的简易加载装置完全能满足材料力学的实验教学要求。
The simple installation of pure dilatational strain experiment on straight beam is popularized in small-sized colleges, but several years＇ usage of this equipment will result in bigger errors, thus affecting the teaching effect. This paper makes an analysis of its advantages and disadvantages, elaborates on the theoretical foundation and initiates an improving process. The improved added installation fully meets the requirements of material mechanics and experimental teaching.
