Abstract
Abstract: In order to numerically simulate and predict the dynamics behavior of a breaking cable, the dynamics model of the underwater cable is built up based on the lumped mass method, and the classical Runge-Kutta method is used to solve the model. The breaking cable is simulated by exerting appropriate boundary conditions. The dynamics behaviors of immediately and slowly breaking cable are studied. The results indicate that the velocity of the nodes around the breaking point reaches the maximum in a very short time, and then the disturbance propagates outside in form of elastic-wave. Tension and velocity distribute more uniformly along the cable in case of breaking slowly, leading to a more uniform distribution of kinetic energy in the cable, The number of nodes with high velocity is reduced and the duration of high velocity motion is shortened; The simulation reveals the mechanism of disturbance's propagation in the form of elastic wave and proves that slow breaking cables are less dangerous than fast breaking ones.
