摘要:
为了提高大摆锤试验机测试结果的准确性,对大摆锤试验机能量测试中的影响因素进行了测试与分析。影响因素主要包括风阻及摩擦损失能量、不同初始能量及锤头速度、不同吸收能量获取方式以及试样的不同缺口形式等。研究结果表明,风阻及摩擦损失能量很小,操作时可忽略不计;不同初始能量及锤头速度对最终试验结果几乎无影响,试验时可根据试样厚度及钢级选择合适的初始能量,减少提锤时间,提高工作效率;E角度编码器E表盘测量结果基本相同,E角度编码器E表盘更为准确,E示波低于E角度编码器;压制缺口试样吸收能量显著高于人字形缺口试样。
Abstract:
In order to improve the accuracy of the big pendulum impact tester testing results, the influence factors of big pendulum tester energy test were tested and analyzed. The influence factors included wind resistance, energy loss of friction,different initial energy, hammer speed, obtain way of different absorption energy, different notch types and so on. The results showed that the energy of wind resistance and energy loss of friction is small, which can be ignored. Different initial energy and hammer speed almost have no impact to final test result, can choose appropriate initial energy according to the specimen thickness and steel grade in testing, so as to lifting hammer time and improve work efficiency; the measuring result of Eangle encoder and Edial plate are basic same, Eangle encoder is more accurate, Eoscillography is lower than Eangle encoder; the absorbed energy of pressed notch specimen was obviously higher than that of chevron notch specimen.
