Wire rope has examined for the total fatigue life prediction methodologies based on the initial condition of the wire rope. The great majority of applications, e.g. cranes, lifts, and winches have been subjected the rope to bending fatigue. There are several parameters which effects on bending fatigue lifetime such as tensile load, sheave diameter, rope composition. Apart from that, according to application area, wire ropes have often exposed to atmospheric influences, and corrosion become inevitable. In this study, in order to determine the exact lifetime of wire rope, corrosion, as a major degradation influence has been investigated experimentally. Bending fatigue tests have been performed for pre-corroded wire ropes with different level of corrosion, and the data have been compared with the reference test results. For comparison of the combine effect of corrosion with tensile loads, and corrosion with sheave diameters, two different tensile loads and sheave diameters have been tested. In this paper, it has been reported the outcome of a series of test undertaken on 6 x 36 Warrington-Seale ropes in order to determine their exact fatigue endurance under different conditions.

腐蚀对钢丝绳弯曲疲劳影响的实验研究

钢丝绳已根据钢丝绳的初始条件检查了总疲劳​​寿命预测方法。绝大多数应用，例如起重机，升降机和绞车，都遭受了绳索的弯曲疲劳。有几个参数会影响弯曲疲劳寿命，例如拉伸载荷，绳轮直径，绳索组成。除此之外，根据应用领域，钢丝绳经常暴露于大气影响，并且腐蚀变得不可避免。在这项研究中，为了确定钢丝绳的确切寿命，已经对作为主要降解影响的腐蚀进行了实验研究。已对具有不同腐蚀水平的预腐蚀钢丝绳进行了弯曲疲劳测试，并将数据与参考测试结果进行了比较。为了比较腐蚀与拉伸载荷和腐蚀与滑轮直径的组合效果，已测试了两种不同的拉伸载荷和滑轮直径。在本文中，已经报道了对6 x 36条沃灵顿-锡尔绳索进行的一系列测试的结果，以确定它们在不同条件下的确切疲劳强度。
