Abstract

See full text

A method for simulating a posture of a flexible cable based on a spring-mass model combining bending and torsion includes: establishing a physical property model of the cable, wherein a torsion property is represented by a torsion spring attached at each 55 cable segment; obtaining an initial position of each discrete mass point based on a total length of the cable and the number of the cable segments; identifying discrete mass points at both ends as fixed points, and obtaining their position information; calculating stress information of other discrete mass points whose position information is not determined based on the physical property model; sequentially calculating 10 10 equilibrium positions of the other discrete mass points by using the stress information and the initial positions to obtain their the position information; and simulating a stable posture of the cable based on the position information of the fixed points and the other discrete mass points.
