钢丝绳索具压制成形仿真分析
|
摘要
钢丝绳索具是广泛运用于海洋工程中起柔性连接作用的有效工具之一,具有强度高、承载能力强、韧性好等优点。由于索具中铝套壁厚的大小与索具承载力密切相关,壁厚的大小最直观的结果就是延伸率,行业中采用控制延伸率为25%～35%的方法实现索具满足承载力的要求。基于SolidWorks-ABAQUS平台,结合显示动力学分析方法对模型的压制成形过程进行仿真分析,并采用控制变量法改变索具接头中铝套的壁厚尺寸,得出索具成形所需压制力、铝套的延伸率以及钢丝绳索具疲劳寿命的变化规律。研究结果显示1X7+IWS-18mm型钢丝绳索具(对应铝套壁厚为7mm)压制成形后最大应力分布在钢丝绳自接触部分,大小为912.6MPa,成形所需压制力为1097.51kN,铝套延伸率为25.53%,疲劳次数为353次。
Wire rope rigging is one of the effective toolswhich iswidely used in margine engineering for the flexible connection,with high strength,strong carrying capacity,good toughness and so on.As the thickness of the aluminum sleeve is closely related to the wire rope rigging's carrying capacity,what the most intuitive result of the wall thickness is the elongation,if the elongation is between 25% to 35%,then it can meet the requirements of carrying capacity in industry.Based on SolidWorksABAQUS platform, combine with the display dynamic analysis method to simulate the pressing process,and the control variate method is used to change the thickness dimension of the aluminum sleeve to obtain the change law of the pressing force,the elongation of the alluminum sleeve and the fatigue life of the wire rope rigging.The forming result showed that the largest stress of the 1 X7+IWS-18 mm wire rope rigging(the thickness of the aluminum sleeve values 7 mm)after pressing distributed in the self-contact part values 912.6 MPa,the formingforce values 1097.51 kN,the elongation of the aluminum sleeve values 25.53%,the fatigue life values 353.
