摘　　要：阐述了落锤撕裂试验能量测试系统在DWTT试验中应用的必要性。通过将国产管线钢落锤撕裂试验能量测试系统的测试曲线与ASTM标准和ZWICK试验机的测试曲线进行对比分析,证明该测试系统的准确性和可靠性;为定量研究各种因素对管线钢断裂韧性的影响以及从理论上分析管线钢承受冲击载荷的断裂机理提供了试验支持。Discussed is the necessity of application of the energy measuring system to the drop-weighted tear test（DWTT）. Based on the result of comparison of the measurement characteristic from the home-made energy measuring system for DWTT for linepipe-purose steel with that from relevant ASTM and ZWICK DWTT machines, it is concluded that the measurement result form the former is accurate and reliable, and it is regarded that the said home-made system is capable of providing testing support to quantitative research on factors responsible for the fracture toughness of the linepipe-purpose steel and the theoretic analysis of the fracture mechanism of the linepipe-purpose steel under impact load.
