钢丝绳是工程中应用极为广泛的一种挠性构件。它具有强度高、自重轻、弹性好、工作平稳可靠、承受动载和过载能力强以及能在高速工作条件下运行和卷绕无噪声等许多优点。在煤炭、冶金、交通运输、建筑和旅游等国民经济各主要行业和部门得到广泛应用。为确保钢丝绳安全、可靠和高效地工作,对钢丝绳的运行状况,如断丝、磨损和锈蚀等缺陷进行检测是非常必要的。 Rope is a kind of flexible member widely used in engineering. It has the advantages of high strength, light weight, good elasticity, stable and reliable operation, strong ability of carrying dynamic and overload, running under high-speed working conditions and noiseless winding. In the coal, metallurgy, transportation, construction and tourism and other major national economy sectors and departments are widely used. To ensure safe, reliable and efficient operation of ropes, it is imperative to test the behavior of ropes, such as broken wires, wear and rust, and other defects.
