- Abstract
The flexible deformation is often neglected in cable modelling on CAD software. To solve the problem, this paper proposes a physical modeling and deformation simulation method for flexible cable under plane constraint based on the nonlinear statics theory of elastic rod. Specifically, a statics equation of the balanced cable was established under plane constraint in the cylindrical coordinate system. Taking the Euler angles as the generalized parameter, the cable space configuration was described through dynamic analogy by the semi-analytical method and the analytical expression in the form of elliptic integral. Then, the simulated cable shapes were compared with the actual shapes under different material parameters and constraint conditions. The results show that the proposed model and numerical solution can fully describe the deformation features of the cable under the plane constraint in an accurate and efficient manner. The research results lay a solid basis for the CAD in cable production.
