Embodiment Construction

[0016] Below in conjunction with accompanying drawing, patent of the present invention is described further.

[0017] as attached figure 1 As shown, the present invention discloses a working principle and a design method of a ship motion control platform. The system is composed of a test bench combining a two-dimensional translation and a three-dimensional motion, a sea state simulation computer, a motion console, and a model computer. 1. The steering gear servo mechanism consists of five parts. The two-dimensional translation test bench is divided into two layers, the lower layer of two-dimensional translation (consisting of X, Y axis guide rails) and the upper layer of two-dimensional translation (consisting of another pair of X, Y axis guide rails and rotating around the Z axis center platform), the upper layer moves relative to the lower layer, and the center platform is installed in the center of the upper layer. The upper and lower floors are controlled by their respe...

Abstract

The invention relates to a ship position motion test platform, which comprises upper and lower layers which make two-dimensional translation, wherein the upper and lower layers are controlled by a motion lock to make relative motion, and a position sensor, a compass and a global positioning system (GPS) are installed on a central platform; a sea condition simulation computer receives current sea conditions input by a keyboard, calculates and simulates the impact of external interference on a ship position and sends a two-dimensional translation command to control the lower layer to be used for simulating the sea conditions, and a ship motion console issues corresponding control commands to a rudder and a side thruster according to the detected ship position; and a ship model computer receives the commands issued by the ship motion console, obtains the current rubber angle and the position of a ship under the action of the side thruster by calculation, issues the two-dimensional translation commands to control the upper layer to move relative to the lower layer, issues rotating commands to control the central platform to rotate, and simulates the deflection of the ship under the action of the side thruster at the current rudder angle. In the ship position motion test platform, the ship parameters and the sea conditions can be arbitrarily set to realize the semi-physical simulation test of the dynamic positioning and automatic berthing or unberthing of the ship.

Description

technical field [0001] The invention belongs to a position-motion control experiment device, and in particular relates to a design concept and a realization method of an object's dual two-dimensional plane motion. Background technique [0002] At present, the common translational motion platforms are mainly two-dimensional translational motion platforms, and some are three-dimensional translational motion platforms such as machining centers. There is no similar product or patent in China for the dual two-dimensional translational motion platform with one-dimensional rotation platform. [0003] The position control experiment platform of the present invention is composed of 5 layers of platforms. The first and second layers of platforms are called the outer layer platform, the reference is the earth, and move along the Y and X axes respectively; the third, fourth, and fifth layers are called the inner layer platform , and also move along the X and Y axes and rotate around th...
