The Dynamic Behavior of Nylon and Polyester Rope under Simulated Towing Conditions.
Abstract
The increasing use of man-made synthetic fiber ropes in the marine environment has generated a need to understand their dynamic mechanical behavior during actual operations. Towing is an operation of primary concern. A method was developed to simulate actual tow conditions with emphasis on constant strain amplitude dynamic loading rather than the more commonly used constant load amplitude dynamic loading. Emphasis was directed towards investigating the change in the dynamic modulus, or stiffness, of the rope when subjected to varying loading conditions, and the change in the hysteresis per cycle of the rope when subjected to varying loading conditions. Finally, measurements were made of the temperature generated during cyclic tensioning and correlations determined between temperature and power input, per cycle. The ropes used were 1/2 inch polyester and nylon rope produced by Samson Ocean Products.
