Embodiment Construction

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

[0017] as attached figure 1 As shown, a ship attitude motion test platform is composed of five parts: a three-dimensional rotating platform, a sea state simulation computer, a motion controller, a model computer, a steering gear and a fin stabilizer servo mechanism. The three-dimensional rotating platform is divided into two layers, that is, the outer layer of the three-dimensional rotation and the inner layer of the three-dimensional rotation. The inner layer moves relative to the outer layer, and the center platform is installed in the center of the inner layer. The inner and outer layers are controlled by their own computers. The outer layer is used to simulate sea conditions, and its computer is called the environment model computer, and the inner layer is used to simulate the movement of the ship under the action of the rudder and fins, and its computer is call...

Abstract

The invention discloses a ship attitude motion testing platform. A three-dimensional rotating platform comprises a three-dimensional rotating outer layer and a three-dimensional rotating inner layer, the locking or unlocking of the inner layer and the outer layer is controlled by a motion lock, and the inner layer and the outer layer are respectively provided with a three-degree-of-freedom sensor. An environmental model computer receives current sea state input through a keyboard command, simulates the influence of external interference on ship attitude through calculation and sends a command to control the outer layer to simulate the sea state, and the sensor feeds back the attitude of the outer layer; a ship motion controller sends a corresponding control command to a rudder and a fin according to the ship (central platform) attitude fed back by the sensor; and a ship model computer receives the control command, calculates out the due ship attitude obtained under the action of the current rudder angle and fin angle, and sends a command to control the inner layer to simulate the motion of the ship under the action of the rudder and the fin. According to the invention, the ship parameters and the sea state can be set freely, and a hardware-in-the-loop simulation test on ship attitude control and automatic stability control of warship canons is realized.

Description

technical field [0001] The invention belongs to an attitude motion control experiment device, and the invention relates to a design concept and a realization method of an object's double three-dimensional rotation motion. Background technique [0002] At present, the most common rotary motion platforms are three-dimensional motion, and there are also a small number of six-degree-of-freedom motion platforms combined with three-dimensional translation. After searching, there are no similar products or patents in China for dual three-dimensional rotary motion platforms. [0003] The double three-dimensional rotary test bench of the present invention is divided into two layers, the outer platform is composed of a frame that rotates around the X, Y, and Z axes, and is respectively driven by three sets of hydraulic servo mechanisms, which can be rotated around the X, Y, and Z axes for arbitrary rotation motion, and equipped with three degrees of freedom sensors. The inner platfor...
