摘要: 为了测试在大拉力载荷下,海底电缆张力弯曲试验装置是否能正常工作,利用有限元分析方法对鼓轮与海缆进行了建模与仿真,并对整个有限元模型进行了应力、应变和位移分析。结果表明,该张力弯曲试验装置在2×106 N的拉力载荷下,应力最大值达到1.05×108 Pa,并未超过碳钢的屈服强度,没有发生大变形,能够正常工作,装置设计方案合理。Abstract: In order to test whether the submarine cable tension bending test device can work normally under high tensile load, the finite element analysis method was used to model and simulate the drum and the submarine cable, and finishing the stress, strain and displacement analysis. The results show that under the tensile load of 2×106 N, the maximum stress reaches 1.05×108 Pa, which does not exceed the yield strength of carbon steel. The overlarge deformation does not occur, and the test device can work normally, which means the design scheme of the submarine cable tension bending test device is reasonable.
