摘要
以某电缆展开式电潜泵系统(CDPS)用复合电缆为原型,基于层合板剪切变形理论和Knapp拉扭理论,建立复合材料与螺旋结构耦合的刚度计算模型,采用有限元方法验证力学模型的准确性。提供了一种实用化高强度电缆刚度计算模型,简化该类电缆计算;通过对电缆铺层方案及动力层缠绕角优化,使电缆拉伸刚度得到了很大的提升。
Taking the composite cable for a cable deployed pumping system （CDPS） as the prototype, a composite and spiral structure coupling simulation model for stiffness calculation was established based on the shear deformation theory of the laminat- ed plate and Knapp torsion theory, whose accuracy was verified the by finite element method. This calcualtion model was suit- able for the high strength cable, and the calculation of the stiffness of the cable was simplified; by optimizing the lay-up design of the cable and winding angle of the dynamic layer, the tensile stiffness of the cable could be greatly improved.
