摘要
文中主要分析6×19+FC型钢丝绳,借助数值分析软件确定了所有绳股轴线和钢丝绳轴线坐标参数序列后,在Matlab中编程生成各根钢丝的空间坐标,导入SolidWorks中生成三维模型。采用耦合约束方法在Ansys里对钢丝绳进行模拟加载,研究钢丝绳受载后的应力分布,得到拉伸载荷下有限元分析结果(最大等效应力、等效应变)。以应力-强度干涉可靠性理论为基础,结合最大应力分布函数及材料强度分布函数,建立钢丝绳在拉伸载荷下可靠度计算模型。经计算分析,钢丝绳可靠度模型满足工程精度。
In this paper,the analysis is mainly focused on the 6×19+FC wire rope,and the coordinate parameter sequences of all strand axes and wire rope axes are determined through a numerical analysis software.Then,the spatial coordinates of each wire rope are obtained by programming in Matlab,and these coordinate data are inputted into SolidWorks and a three-dimensional model is established.By using the coupling constraint method to simulate the loading of steel wire rope in Ansys,the stress distribution of steel wire rope under load is studied,and the finite element analysis results(maximum equivalent stress and equivalent strain)under tensile load are obtained.Based on the stress-strength interference reliability theory,combined with the maximum stress distribution function and the material strength distribution function,the calculation model of the reliability of steel wire rope under tensile load is established.Through calculation and analysis,it can be seen that the reliability model of wire rope meets the requirements of engineering precision.
