Virtual Prototype Study of a Boom-Type Offshore Transmission for Wind Power Operations and Maintenance

In order to solve the safety problems of non-contact operation and personnel transfer between operation and maintenance vessels and offshore wind turbines, a boom structure of the jib type offshore transmission device with a lift and sink compensation function is proposed. This paper takes the offshore transmission device and the six-degree-of-freedom motion platform as the research object, bases on the method of software co-simulation, uses Simcenter 3D motion to build its dynamics modelling, simulates the lifting and sinking motion caused by the waves in MATLAB, and then transfers it to the hydraulic system established by AMESim through the interface module to carry out the solution, so as to complete the virtual prototype design and simulation of the offshore transmission device. The simulation results show that the transmission device can substantially reduce the influence of waves on its motion under the effect of rise and sink compensation, which provides a theoretical basis for its physical model and an idea for the simulation of other complex electromechanical-hydraulic systems.
