Design and Analysis of a Five-Degree-of-Freedom Moving Platform for Deep-Sea Laser Cladding

The deep-sea in-situ laser cladding is an important technique for the construction and maintenance of the deep-sea equipment, which faces the complicated working condition and harsh ocean environment. To achieve this purpose, a five-degree-of-freedom moving platform (5DOFMP) for deep-sea laser cladding is proposed. First, the mechanical structure of 5DOFMP is designed, which can accomplish the position and posture adjustment of laser cladding device. Then, the kinematic characteristic of the 5DOFMP is investigated. To satisfy the mentioned requirements, a hydraulic system is designed for the 5DOFMP. Finally, the performance of the hydraulic system is simulated and analyzed, which demonstrates that the designed hydraulic system can realize the stable control of laser cladding device in the deep-sea environment. The developed 5DOFMP will promote the development of the deep-sea laser cladding.
