摘要
钢丝绳常规的力学检测有其自身的局限性,无法对结构设计中存在的问题进行评价分析。通过测量8x19s、6x25Fi样品钢丝绳的结构参数和使用现有相同结构的理论参数分别建立2种模型,利用ANSYS有限元对比分析了2种钢丝绳的结构内部在加载条件相同时的等效应力分布,并通过验证试验证明了模型分析具有一定合理性。结论认为,测定钢丝绳的绳、股、单丝的直径,以及绳、股捻距,可以快速简便的建立钢丝绳实物的模型结构,并能利用ANSYS有限元的模拟结果进行评价性分析。
The conventional mechanical testing of steel wire rope has limitations,and it is unable to evaluate and analyze the existing problems in structural design.By measuring the structural parameters of 8 x19 s,6 x25 Fi steel wire rope and using the existing theoretical parameters of the same structure to establish two models,the ANSYS finite element analysis of the structure of the two types of equivalent stress distribution at the same loading conditions,and through the verification test proved that the model analysis is reasonable.It is concluded that the model structure of wire rope can be established quickly and simply by measuring the diameter of wire rope,strand and single strand,as well as the twist distance of rope and strand,and the evaluation analysis can be carried out by using the simulation results of ANSYS.
