Abstract

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.
