The invention discloses a seven-degree-of-freedom motion simulation platform for simulating marine swing of a ship, and aims to solve the problem that the existing six-degree-of-freedom simulation platform cannot completely simulate and reproduce conditions encountered by a ship body under complex sea conditions. The single-degree-of-freedom rotary table is installed on the upper table face, rotation control is achieved through driving of a Z-axis motor on the single-degree-of-freedom rotary table and meshing between a driving wheel and a driven wheel, the six-degree-of-freedom platform adopts a parallel mechanism scheme, and a servo motor is used for driving tangential swing rods to control the distance between six supporting points annularly and evenly distributed on the upper table face and the lower table face. And translation and rotation in X, Y and Z directions are realized. Through the synergistic effect of the six-degree-of-freedom motion platform and the single-degree-of-freedom rotary table, most of conditions, such as compound motion of swaying, surging, heaving, rolling, pitching, yawing and the like, encountered when a ship sails on the sea can be simulated, rotation around the Z axis and 360-degree rotation of the seventh degree of freedom can be achieved at any position, and continuous and dead-point-free effects are achieved.
一种模拟船舶海上摇摆的七自由度运动模拟平台,以解决现有六自由度模拟平台不能完全模拟和再现船体在复杂海况上遇到的情况的问题。本发明的单自由度转台安装于上台面,并通过单自由度转台上的Z轴电机驱动,主动轮与被动轮之间的啮合实现转动控制,六自由度平台采用并联机构方案,利用伺服电机驱动切向摆杆式控制六个环形均匀分布在上下台面的支点之间距离,实现X、Y、Z方向的平动和转动。六自由度运动平台与单自由度转台的协同作用不仅可以模拟船舶在海上航行时遇到的大部分情况,例如横荡、纵荡、垂荡、横摇、纵摇、艏摇等的复合运动,还可以在任意位置实现第七自由度绕Z轴转动及360°回转,连续无死点。
