Device for testing pier collision system based on ship anti-collision device and test method thereof

Abstract

The invention discloses a device for testing a pier collision system based on a ship anti-collision device and a test method thereof. The device comprises ropes, a fixed end, a pendulum, a housing, a locking device, an anti-collision device, a concrete column, and a water pool; wherein the water pool is filled with water, the concrete column is vertically fixed in the water pool, one side of the anti-collision device is next to one side of the concrete column and is fixedly arranged, the housing simulates a ship floating on the water in the water pool, and a short distance is kept at the front end of the housing which is next to the other side of the anti-collision device; the pendulum can perform fixed axis rotation about the fixed end by the ropes; the pendulum is released after being lifted and then performs movement in a curve entering from the rear end of the housing; a synchronous movement integral unit is formed by the pendulum and the housing through the locking device when the pendulum swings to the lowest point and the integral unit collides with the anti-collision device. The invention discloses a device for testing a pier collision system based on a ship anti-collision device and a test method thereof; water influence is taken into consideration and the collision between ships and anti-collision devices under water environment is realistically simulated.

Description

technical field [0001] The invention relates to a pendulum impact test device of a ship-anti-collision device-bridge pier collision system, which can truly simulate the collision between a ship and an anti-collision device in a water environment. Background technique [0002] At present, accidents of ships colliding with bridge piers occur frequently, which often cause damage to bridge piers and ships, and bring major safety hazards and property losses. In order to take corresponding countermeasures, the experiment should be designed to simulate the collision process of the ship first. The collision between the ship and the anti-collision device or bridge pier occurred in a water environment, and the impact of water on the collision was not considered in a large number of previous collision tests, which is undoubtedly inaccurate. In order to improve the accuracy of the test, the test device in the present invention fully considers the influence of water in the collision pro...
