Summary on Grant Application Form |

1. To conduct a theoretical investigation of the dynamic stability of cable body systems to gain insight into the intrinsic nature of these systems. 2. To develop a robust numerical approach to simulate chaotic motions for a general mathematical model of taut slack cable body systems. 3. To perform a simple experiment to verify the theoretical results. 4. To undertake a parametric study to identify the key factors in preventing chaotic motions. (1) Basic characteristics study. An analytical study will be conducted for simplified cases to reveal the basic characteristics of the system and to examine the loss of stability. To begin with, for example, a single degree of freedom model with a linear damping term may be employed to study the heave motion of the system. (2) Numerical analysis. It is envisaged that the taut slack cable body system, working in a multi dimensional space with non linear damping, will not generally be amenable to analytic study. Numerical simulation must be employed. An accurate, yet robust, numerical scheme must be developed to simulated chaotic motions in the time domain. The mathematical model adopted in previous research will be employed, with modifications when necessary. The key issue is the development of fast algorithms to make the computation feasible. (3) Experimental study. This involves a 1D cable body system (constrained by guidelines) oscillating vertically in an alternating taut slack condition, subjected to a wide ranging excitation. The test includes recording and subsequently analysing the system motion,measuring the associated snap loading, and examining the effect of damping. (4) Parametric study.
