摘要
以6×36 P.WS-IWRC面接触钢丝绳为研究对象,在自制的多层卷绕钢丝绳磨损试验装置上开展了双折线式多层卷绕钢丝绳损伤与失效行为试验研究,探索了双折线式多层卷绕钢丝绳损伤失效机理。结果表明,双折线式多层卷绕过程中钢丝绳间相互挤压与摩擦滑动引起的外层钢丝磨损与塑性变形是导致钢丝绳外层丝断裂失效的主要原因;钢丝绳承受的损伤大小与其在卷筒上的卷绕位置密切相关,呈"斜楔"式排列的卷筒跃层爬升段及相邻区域钢丝绳卷绕过程承受的损伤最为严重。钢丝绳外层钢丝断裂机理分析表明,外层钢丝断裂行为与钢丝表面塑性流动层内形成的白层组织有关。
A 6 X 36 P. WS--IWRC facial contacted wire rope was taken a~ Lnc ~ ~ J plore the damage failure mechanism of wire ropes in parallel grooved multi--layer winding by the damage and the failure behavior test was carried out on a self--made multi--layer winding wire rope wear test apparatus. The results show that, in parallel grooved multi -layer winding, the wear and deformation of outer layer wires caused by the wire rope squeezing and frictional sliding each other was the main reason of wire breakMg. The damage value of the wire rope is related closely to winding position in the drum, and the damage during the wire rope winding in crossover zone at the end of each--layer drum is the most serious. Furthermore, the fracture behavior of outer layer wires is relat- ed to the white layer structure which is on the surface of the wire for analyzing the fracture mechanism of outer layer wires in the rope.
