Abstract
A cam mechanism type ship shaking simulator comprises a frame, a control terminal, a ship model, an experimental chamber, a driven wheel, a top rod, a limiting guide rail, a power cam set, at least one frame bearing group, a side-surface rotating shaft, a side-surface bearing and a detection black box; the bottom of the ship model is provided with a magnet, and the detection black box is arrangedin the ship model; a simulated environment liquid and the ship model are filled into the experimental chamber, the experimental chamber is connected with the top rod via a spherical pair mounted in the side surface of the experimental chamber, and the experimental chamber is connected with the side-surface rotating shaft via the side-surface bearing arranged at the other side of the experimental chamber; the top of the top rod is connected to the side surface of the experimental chamber via the spherical pair, and the bottom of the top rod is hinged to the driven wheel; the limiting guide railis fixedly connected with the frame; the power cam set is arranged under the driven wheel, is in sliding connection with the driven wheel, and is fixedly connected with the frame; the frame bearing group is arranged on the frame and connected to the side-surface rotating shaft; the side-surface rotating shaft is connected with the frame bearing; the middle of the side-surface bearing penetrates the side-surface rotating shaft, and is fixedly connected with the experimental chamber. The simulator includes fewer compositions and is long in service life, and the cam structure can be used to switch different simulated ship shaking motions.
Description
technical field [0001] The device relates to a ship model simulation device, in particular to a cam mechanism type ship sloshing simulation device. Background technique [0002] At present, there are many ship sloshing simulation devices, such as ship two-degree-of-freedom motion platform, ship four-degree-of-freedom motion platform, ship six-degree-of-freedom motion platform, etc., which have compact structure, strong bearing capacity, good rigidity, small error, and dynamic Good performance, etc., but there are also deficiencies such as various composition structures, complex operations, and high production costs, and it also needs to combine robotics, machine tool technology, computer numerical control technology, vibration control technology, multi-coordinate numerical control programming and other technologies; There are many aspects such as position positive solution, flexibility, work space, stiffness and accuracy, dynamic modeling and optimization, control algorithm,...
