Abstract: 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 laminated plate and Knapp torsion theory, whose accuracy was verified the by finite element method.This calcualtion model was suitable 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.
