Lifetime of large twisted and tension-tension loaded wire ropes

拟议的研究项目旨在建立在Wehking /Ernst于2011年进行的12毫米测试系列的基础上，对拉力和扭转载荷对钢丝绳寿命的尺寸影响有一个基本的了解。此外，还应开发一个有用的数据库，用于计算和解释海上使用的2万多根直立拉索。研究结果将使拉力载荷钢丝绳在耐久性方面发挥其优越的潜力。此外，还关闭了先前未知的扭转影响方面的安全漏洞。缆绳应该像在IFT中进行的测试和积极的同行评审的研究项目一样进行测试，在张力-张力测试中系统地改变相关参数以断裂。评价采用Wehking / 2011 Ernst生成的计算基础进行。相关参数定义如下：绳施工、2。钢丝绳直径,3。4.电线绕其纵轴的扭转。张力幅值-张力荷载和5。张紧载荷的欠载。

The proposed research project aims to develop a basic understandingof the size effect on the life of wire ropes with combined tensiontensionand torsional loads, building up on the test series of Wehking /Ernst conducted in 2011 with 12 mm. In addition, a useful data basefor the calculation and interpretation of standing guy ropes, more than20,000 in the offshore area in use, shall be developed. The results willenable tension-tension loaded wire ropes to use their superiorpotential in durability. In addition, a security vulnerability in terms ofpreviously unknown influences in torsion is closed. The ropes should be tested as in the at IFT performed and positive peer reviewedresearch project with systematic variation of the relevant parametersin tension-tension-tests to break. The evaluation is done using thegenerated in Wehking / 2011 Ernst basis of calculation. The relevantparameters are defined:1. rope construction,2. rope diameter,3. twisting of the wire about its longitudinal axis,4. amplitude of the tension-tension load and5. underload of the tension-tension load.
