Problems solved by technology

The active and passive compensation device is a combination of the active compensation device and the passive compensation device. However, there are still few researches on the active and passive compensation device. In order to fully optimize the design of the active and passive wave compensation device, a wave prediction, tension compensation, speed The control algorithm of compensation and displacement compensation, to promote the commercialization of domestic heave compensators, now urgently needs an active and passive heave compensation experimental device to provide an experimental environment for heave compensation control algorithm and debugging

Abstract

The invention discloses an active and passive wave compensation experiment device. The device comprises a wave simulation platform, a load suspending system installed on the wave simulation platform,and an active and passive wave compensation system connected with the load suspending system. The wave simulation platform comprises a fixed pedestal, and a platform is disposed above the fixed pedestal. The fixed pedestal is connected with the platform through a six-freedom-degree simulation hydraulic cylinder. The device employs the six-freedom-degree wave attitude simulation equipment as the wave simulation platform, can achieve the prediction of the motion trend of the platform in the future takt time, and takes the corresponding compensation measures. The active and passive wave compensation experiment device can provide a real experiment environment for the research and debugging of a wave compensation prediction algorithm. The experiment device employs a variable pump as the drivingforce, and improves the loading capability.

Description

Technical field: [0001] The invention relates to a wave compensation experimental device, in particular to an active and passive wave compensation experimental device. Background technique: [0002] With the development and utilization of marine resources and the continuous improvement of marine development technology, the types and quantities of offshore operations in my country are increasing. Different from the land environment, the offshore operation environment is harsh and will be affected by wind, waves, and currents, which will cause the hull to turbulent, so that the hoisted heavy objects will inevitably produce pitch, roll, yaw, surge, sway, Heave and its coupled motion greatly affect the efficiency and safety of offshore operations. For this reason, a wave compensating device is added to the existing offshore operation equipment to solve the above problems. [0003] The current heave compensation devices mainly include three types: active compensation, passive c...
