Embodiment Construction
[0024] The methods described in the following examples are conventional methods unless otherwise specified.
[0025] like Figure 1-Figure 4 , is the compression type fender pre-tensioning simulation device of the present invention, it consists of elastic deformation part ( figure 2 ), limit rail part ( image 3 ) and the pretensioning part ( Figure 4 ) consists of three parts;
[0026] Wherein, the elastic deformation part is made up of at least one compression spring 1, the connection cushion block 2 fixed on the two ends of each compression spring 1, the model contact block 3 and the connection support member 4; the connection cushion block 2 fixed at one end of compression spring 1 and The connection supporting part 4 is fixedly connected, and the other end of the pressure spring 1 is fixed to the connection cushion block 2 and the model contact block 3 is connected. The model contact block 3 can be provided with one or more compression springs as required to connect...

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 ofthe 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 articlerounds 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
[0001] The invention has applied for a utility model patent at the same time technical field [0002] The invention relates to a compression type fender pretensioning simulation device. Background technique [0003] 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. [0004] 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. [0005] Among them, the stiffness curve of compression fender has obvious characteristics, which consists of three sections: ① linear section, ② free defor...
