| Abstract: | Discrete model of flexible cable with large sag is established by using multiple rigid body_spherical hinge model, and dynamic equation of that discrete model is derived according to dynamics theory of multiple rigid body system. Displacement and velocity of system are revised to eliminate violation phenomenon of the differential_algebra equation in numerical simulation based on the theory of generalized inverse of matrices. Numerical simulation proves the validity of our method. |
| Keywords: | flexible cable with large sag multiple rigid body system dynamics numerical simulation violation correction |
