Abstract

The invention discloses a multi-degree-of-freedom active type wave compensation simulator based on a parallel mechanism. A hydraulic cylinder drives a six-degree-of-freedom parallel platform to move, so that the motions of a supply ship and a ship to be supplied affected by wave are completely simulated; a hydraulic motor is used as a rotation system of a power supply to drive a wave compensation winch and a crane, so that the situation that cargoes are rotated at a certain angel from the supply ship and are then lifted and put to the ship to be supplied through wave compensation is simulated; and a wave compensation terminal parallel platform is used for eliminating the shaking of the crane during a rotation process and carrying out multi-degree-of-freedom wave compensation, so that the cargo supply between the two ships is finally realized. According to the multi-degree-of-freedom active type wave compensation simulator based on the parallel mechanism provided by the invention, under the drive of the hydraulic cylinder and the hydraulic motor, the simulator has the characteristic that cargo lifting and putting between the two ships and wave compensation supply thereof can be simulated visually, and can be applied in the development and the performance test of a wave compensator.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery and relates to a multi-degree-of-freedom active wave compensation simulation system based on a parallel mechanism. Background technique [0002] During the voyage of the ocean-going fleet, due to the long voyage distance and long time, it is often accompanied by some special supply ships, especially when the supply ships supply the fleet with explosive goods such as ammunition, they are often easily deformed due to impact due to the influence of waves. It is absolutely unacceptable to even cause an explosion, so it is necessary to solve this problem. [0003] Chinese patents 201420599459.3, 201410195456.8, 201610910292.1, 201620399367.X, 201210219968.4, 201520111650.3, etc. all propose to use a wave compensation system similar to that of a boat system based on a constant tension winch, without measuring the relative distance or angle between the two ships , not active heave compensa...
