The invention belongs to the technical field of wave compensation, and discloses a three-degree-of-freedom series-parallel wave compensation platform and a compensation method.The compensation platform comprises a platform base fixedly installed on a ship and provided with the height direction, and further comprises a transverse and longitudinal shaking platform, two electric cylinders arranged above the platform base in the height direction, and a connecting rod, the fixed ends of the two electric cylinders are hinged to the platform base, and the free ends of the two electric cylinders extend in the height direction, are jointly hinged to the transverse pitching platform and are used for being connected in parallel on the transverse pitching platform to form transverse pitching freedom degrees; and the heaving electric cylinder is arranged on the transverse and longitudinal rocking platform, the free end of the heaving electric cylinder supports the heaving platform and is used for forming a heaving freedom degree, and the heaving electric cylinder is connected with the two electric cylinders in series to form a three-freedom degree. According to the invention, the platform structure form is adjusted into a series-parallel connection degree of freedom, the number of driving levers is reduced, a four-cylinder statically indeterminate structure in the prior art is avoided, errors are avoided, and potential threats to the life safety of personnel and equipment on the operation platform are reduced or avoided.
本发明属于波浪补偿技术领域,公开了一种三自由度串并联波浪补偿平台及补偿方法,该补偿平台包括固定安装在船舶上的平台基座,平台基座具有高度方向,还包括,横纵摇平台,沿高度方向设在平台基座上方,两个电动缸,其固定端均与平台基座相铰接,且两个电动缸的自由端均沿高度方向延伸并共同铰接横纵摇平台,用于在横纵摇平台上并联形成横纵摇自由度;升沉电缸,设在横纵摇平台上,且其自由端支撑升沉平台,用于形成升沉自由度,并与两个电动缸串联形成的三自由度。本发明将平台结构形式调整为串并联自由度,减少驱动杠的数量,避免现有技术中四缸超静定结构,不会出现误差,降低或者避免对作业平台上的人员生命安全和装备构成潜在威胁。
