THE INFLUENCE OF THE SYNTHETIC ROPE ELASTICITY TO ITS SHAPE AND THE TENSION IN CROSS FLOW
Previously obtained empirical formulas were used to account for the elastic properties of ropes at their balance in the water flow. The self-similar region of hydrodynamic resistance was investigated. The shape of the rope can be considered as parabolic for small values of the boom deflection. The problem of equilibrium can be solved approximately. Nonlinear algebraic equation for determining the deflection of a stretched rope was obtained after the integration. Under the given characteristics of elasticity by the similarity criteria of the problem are the Froude number, the ratio of water density to the density of the material and the magnitude of the deflection of unstretched rope. Neglecting the elasticity of the rope in the above conditions leads to an overestimation of the calculated tension force in several times.
