摘　　要：大型起重机械钢结构损伤声发射检测受到其机械结构不连续导致声波传输路径杂乱、动载噪声干扰大等因素影响,其应用受到了极大的限制。本文将从材料损伤声发射源机制试验分析及现场检测两个方面对起重机械结构损伤声发射检测的可行性进行探讨,从而为声发射技术在大型起重机械金属结构损伤方面的应用提供科学的基础理论研究成果支撑。The Acoustic Emission testing application on Crane steel structure is greatly limited,because factors such as the random transmission path of sound wave,the influence of dynamic load noise and the discontinuity of structure.In this paper,the feasibility of Acoustic Emission detection for crane structure damage is discussed from two aspects:mechanism test and field detection,so as to provide the scientific basic theoretical research results support for the application of acoustic emission technology in the metal structure damage of heavy lifting machinery.
