A Feasibility Study of the Hybrid Simulation Technique as Applied to Large Scale Cable Dynamics,

Abstract

The development of a hybrid computer implementation for the equations of motion for an elastic cable in two dimensions is presented. The discrete element approach is used, in which the partial differential equations that represent the dynamics of the cable system are reduced to a set of 2N ordinary differential equations representing N nodes. A time share procedure is developed in which analog components are shared for different sections of the cable. The basic features of switching from one section to the next, and the logic that controls it, are developed using a simple second order system of two coupled equations. Then a sample cable problem (six foot buoy release using four nodes) is implemented in full on the hybrid computer, and the results are compared with solutions obtained by an all digital technique.
