Multi-parameter coupled liquid-carried ship collision test device and test method

Abstract

The invention discloses a multi-parameter coupled liquid-carried ship collision test device, which comprises a water pool, a data acquisition system, and a colliding ship, a collided ship, a collidingship traction and guiding device and a collided ship traction and guiding device, which are arranged on the water pool. The data acquisition system comprises a CPU, a wireless communication module, astorage device, a plurality of wireless pressure sensors and a plurality of wireless displacement sensors. The colliding ship is connected with the colliding ship traction and guiding device; the collided ship is connected with the collided ship traction and guiding device; the CPU is electrically connected with the wireless communication module and the storage device; and the CPU is electricallyconnected with each wireless pressure sensor and each wireless displacement sensor through the wireless communication module. The device and method carry out multi-parameter coupled liquid-carried ship collision test by changing relevant parameters of the colliding ship, relevant parameters of the collided ship and water volume in the water pool to obtain influence of different parameters on testresults.

Description

technical field [0001] The invention relates to the technical field of ship manufacturing, in particular to a multi-parameter coupled liquid-carrying ship collision test device and test method capable of studying the influence of various parameters on the collision test results. Background technique [0002] With the continuous growth of global energy demand, VLCCs and FPSOs are carrying more and more loads, and their speeds are increasing, and the routes are becoming more and more congested, increasing the possibility of ship-to-ship collision accidents. The consequences of ship collision accidents are very serious, especially the collision accidents of tankers such as oil tankers, so it is necessary to study the collision damage of liquid-carrying ships. [0003] At present, there are mainly four methods for the research of ship collision: test method, empirical formula method, simplified analysis method and numerical simulation method. Since ship collision is a very comp...
