Guide wheel type elastic rope simulation device and application method

Abstract

The invention provides a guide wheel type elastic rope simulation device. According to the device provided by the invention, one side of a model cable rope is connected with an acting object and the other side of the model cable rope is connected with heavy blocks through a guide wheel; a pull force of an elastic rope is simulated through the gravity of the heavy blocks and rope deformation caused by corresponding pulling force effect is controlled through the distance between the heavy blocks; a spring is arranged between the heavy blocks and the deformation of the elastic rope under the adjacent pulling force effects is linear. Non-linear deformation of the elastic rope under the pull force effect is transformed into a plurality of linear deformation; deformation of the rope at an important pull force node (a rope end breaking force and the like) is accurately controlled, so that a pull force-deformation relation of the elastic rope can be more accurately reflected from a model test. The guide wheel type elastic rope simulation device provided by the invention can be used for accurately simulating a pull force deformation property of an actual rope and is applicable to elastic rope simulation of ship mooring, large-size structure anchoring and the like; the guide wheel type elastic rope simulation device can be popularized and applied to rope simulation of other types of model testes.

Description

technical field [0001] The invention belongs to laboratory test equipment for port waterway engineering, and in particular relates to a guide wheel type elastic rope simulation device and an application method. Background technique [0002] With the rapid development of marine economy, coastal resources have been further developed, and deep-sea economy has been paid more and more attention. Large-scale ships and deep-water docks have become an inevitable trend, but with it, engineering construction will also face increasingly harsh natural conditions. The mooring of ships and the anchoring of large structures usually use high-strength cables to connect with fixed piers to ensure safety. The force of the cable has a very complicated relationship with the movement of the ship. It not only involves the nonlinear constraints on the ship such as the mooring force, but also involves the effects of wind, water flow and waves, and different berth layout schemes such as the length o...

Problems solved by technology

However, none of the above methods can accurately simulate the tension-deformation curve of the actual rope (that is, the tension-deformation characteristics of the actual rope cannot be accurately simulated).

On the one hand, repeated experiments are required, which is time-consuming and the simulation effect is poor; on the other hand, due to the variety of ropes used in actual engineering and the limitation of the test scale, it is difficult to find a convenient and general method to simulate elasticity. rope
