Forming Simulation Analysis of Wire Rope Sling that Combined Casing

针对高强度要求的固结钢丝绳索具,提出新型的复合型钢套加铝合金套固结方式,并基于SolidWorks-ABAQUS平台对钢套与铝合金套复合方式及其配合间隙大小进行仿真研究。采用单因素控制变量法分别改变钢套与铝套之间的间隙(0~5)mm及其复合方式(铝套--钢套、钢套--铝套),得到了钢丝绳的应力分布特性和变化规律。仿真分析表明,采用钢套--铝套的复合方式进行压制成型的钢丝绳复合套索具其钢丝绳应力随着复合间隙的增大呈"锯齿状"递增,在"零间隙"时钢丝绳最大应力值最小,为897.8MPa,且应力分布均匀,应力波动为6.4%,能有效改善钢丝绳力学工作性能,更好的满足使用需求。

In this paper,a new type of composite steel sleeve with aluminum alloy sleeve is proposed for the steel rope rigging with high strength requirements,and the composite mode of steel sleeve and aluminum alloy sleeve and the size of fit clearance are simulated based on SolidWorks-ABAQUS platform.The single factor control variable method is used to change the gap(0~5)mm between the steel sleeve and the aluminum sleeve and its combination mode(aluminum-steel sets or steel--aluminum sets)respectively,and the stress distribution characteristics and variation law of the wire rope are obtained.The simulation results show that the steel wire rope composite rigging used in compression forming with steel-aluminum sets the wire rope stress increases with the increase of the composite gap in the form of"sawtooth",and the maximum stress of the wire rope is the smallest when the gap is zero,it is 897.8MPa,and the stress distribution is uniform,the stress fluctuation is 6.4%,which can effectively improve the mechanical performance of the wire rope and better meet the needs of application.
