The invention belongs to the field of ocean engineering, and particularly discloses a six-degree-of-freedom platform device for simulating an offshore floating platform, the six-degree-of-freedom platform device comprises a fixed platform and a movable platform, three movable seats are distributed on the fixed platform in an annular array, two electric cylinders are hinged to each movable seat, three pairs of hinge points are distributed on the bottom surface of the movable platform in an annular array, and two electric cylinders are hinged to each electric cylinder. The upper end of each electric cylinder is hinged with a corresponding hinge point on the bottom surface of the moving platform, so that the moving platform performs six-degree-of-freedom motion output of three-rotation and three-movement relative to the fixed platform; a driving assembly for adjusting the position of the movable seat is arranged on the fixed platform, and the driving assembly comprises three linear guide rails embedded in the fixed platform in an annular array; a plurality of buffering assemblies are connected between the limiting ring on the outer edge of the base and the side edge of the fixed platform. A locking mechanism for locking the fixed platform and the base is embedded in a rotating shaft on the bottom surface of the fixed platform; and a data acquisition module for acquiring pose and stress data of the motion platform is embedded on the motion platform.

    本发明属于海洋工程领域,具体公开了一种模拟海上浮式平台的六自由度平台装置,包括固定平台以及运动平台,固定平台上呈环形阵列分布有三个移动座,各移动座上分别铰接有两个电动缸,运动平台底面呈环形阵列分布有三对铰接点,各电动缸上端与运动平台底面对应的铰接点铰接,使运动平台相对固定平台进行三转动和三移动的六自由度运动输出;固定平台上设置有调整移动座位置的驱动组件,所述驱动组件包括呈环形阵列嵌装在固定平台上的三个直线导轨;底座外沿的限位环和固定平台侧边之间连接有若干缓冲组件;固定平台底面转轴内嵌装有将固定平台与底座锁定的锁止机构,所述运动平台上嵌装有用于采集运动平台的位姿及受力数据的数据采集模块。
