Abstract

The invention discloses a simple sea motion simulation platform device, which comprises a base, the base is provided with a vertical guide rod, a support frame is sleeved on the guide rod to be matched with the guide rod in a sliding way, a swinging rod is fixed on a first electrical machine arranged on the base, the swinging rod is matched with a guide way arranged on the support frame by a slide block, the support frame is provided with a second electrical machine, one end of a material carrying platform is articulated with the support frame, and the other end of the carrying platform is matched with a cam wheel of the second electrical machine. The first electrical machine, the swinging rod, the second electrical machine and the cam wheel form into a 'sine-cam wheel' mechanism. The sine-cam wheel realizes the motion on the direction of rising and sinking, realizes the motion on the transverse direction, mutually overlaps the two motions, can respectively control the rotation speeds of the two drive motors though an adjustable resistor, realizes the adjustability of the motion frequency on two directions, and can adjust the amplitude on the direction of rising and sinking by changing the operating distance of the swinging rod.

Description

technical field [0001] The invention belongs to a sea wave simulation platform device, in particular to a simple sea wave motion simulation platform device capable of simulating two-degree-of-freedom motions of deck heave and heel when a ship sails or operates at sea. Background technique [0002] When a ship is sailing or operating at sea, the materials consumed must be continuously replenished at sea. However, in the case of wind and waves at sea, the ups and downs of the waves will cause the relative movement between the supply ship and the supplied ship, which poses a great threat to the safe operation of the supply at sea. Therefore, the wave compensation system can improve the comprehensive performance of the wave compensation system and realize the all-weather safe supply of marine materials. At present, there are various structural forms of heave compensation systems, which are mainly divided into two types of heave compensation systems: follow-up and active heave c...
