Sea condition simulation device of ship

Abstract

The invention discloses a sea condition simulation device of a ship. The sea condition simulation device of the ship can simulate stress alternation situation of the ship in a marine environment and provides a reference basis for ship design and check. According to the sea condition simulation device of the ship, by using a parallel mechanism to construct a six-degree-of-freedom platform, requirements on various motion attitudes of the ship in the marine environment are satisfied; four wave blasting devices are uniformly distributed on the surrounding of the ship; through combination between the wave blasting devices, the propelling tendency and strength of the waves can be simulated; as circular point clamping heads and sucker clamping heads are distributed in a crossed manner, the inclined surface of a hull can be stably clamped; and as a vortex generating device and an air blower set are arranged, sea vortexes and sea storms can be simulated; and under the coordination of specific smog, the pneumatic streamline situation of the hull can be very well displayed. According to the sea condition simulation device of the ship, the design mechanism is special, the sea severe environment and the hull stress condition are simulated in a maximized manner, and deflection and moving attitudes of the hull are monitored in real time under the coordination of recognition of a vision camerato provide an important reference basis for hull design and manufacturing.

Description

technical field [0001] The invention provides a ship sea state simulation device, which belongs to the field of ship sea state simulation device design. Background technique [0002] In harsh sea conditions, the ship will produce large heaving and swinging, which will bring adverse effects on the operation of the equipment on board. In order to test the influence of the vibration caused by random sea waves on the performance and reliability of ship equipment, a six-degree-of-freedom sea state simulator is used to reproduce random sea waves, and the ship equipment is subjected to environmental simulation tests to check whether the ship equipment can meet the operating requirements under severe sea conditions. At the same time, it is also used to determine the level of sea conditions in which the ship is not suitable for sailing to ensure the safety of the ship's navigation.

AI Technical Summary

Problems solved by technology

[0003] Domestic and foreign companies have mastered wave random vibration simulation technology and simulation devices. These devices are mainly used for small-amplitude random vibration simulation. The disadvantage of this device is that the stroke is relatively short

The wave amplitude is large in severe sea conditions, so it cannot be simulated by general vibration simulators
