不同摆锤刀刃半径对室温冲击试验结果的影响
Influence of Different Striker Blade Radius on Impact Test Results under Room Temperature
摘要
Abstract
The national standard GB/T 229-2007 specifies the striker blade radius can be chosen as 2 mm and 8 mm- There must be a certain difference between them. So the impact performance was tested under room tem- perature for the same samples by two kinds of different radius blade. The results showed that the impact absorption power by 8 mm radius blade was greater than by 2 mm radius blade, but the difference was not obvious. The right method and corresponding blade radius should be chosen to avoid misjudgement results. When the impact perform- ance of different materials was compared, only using the same radius blade, the results were comparable.关键词
