Device for simulating pre-tensioning of compression-type fender

Abstract

The invention discloses a device for simulating pre-tensioning of a compression-type fender, consisting of an elastic deformation part, a position-limit guideway part and a pre-tensioning part; the position-limit guideway part comprises a guideway, a guideway sliding block and a pulley that is fixedly arranged at one end of the guideway; the elastic deformation part is fixedly connected with the guideway sliding block of the position-limit guideway part; the pre-tensioning part consists of a pulley, a heavy block, a pulley bracket and a filiform article that is capable of bearing the weight of the heavy block; the pulley bracket supports the pulley; one end of the filiform article is connected with the heavy block and hangs the heavy block in the air; the other end of the filiform article rounds the pulley and is then connected with the guideway sliding block or the elastic deformation part. The device can simulate three sections of rigidity characteristics with large property differences, and can adjust the corresponding free deformation section distance and the minimum reaction force value in the rigid stage according to the characteristic value needed by the target rigidity curve; therefore, the device utilize one model to simulate a plurality of entities with different rigidity characteristic values and can be widely used for simulating various devices that have similar rigidity characteristic with the compression-type fender.

Description

technical field [0001] The invention relates to a compression type fender pretensioning simulation device. Background technique [0002] In today's offshore oil development, whether FPSO, fixed or mobile platforms are used, it is very common to use shuttle tankers to transport oil back and forth between terminals and offshore oil production facilities. [0003] When the shuttle tanker berths on the platform, in order to prevent the collision between the tanker and the platform and damage the platform or tanker, a ship berthing frame is generally installed on the side of the platform, and multiple rubber fenders are installed at both ends of the ship berthing side. To absorb the impact kinetic energy of the tanker and reduce the impact force. [0004] Among them, the stiffness curve of compression fender has obvious characteristics, which consists of three sections: ① linear section, ② free deformation section, and ③ restricted deformation section. Due to its special stiffn...
