Finite Element Optimization Design Of Deployment & Recovery Winch Structure Based On Pro/Engineer,Ansys

The mooring wire winch is the main auxiliary machinery in ocean development. 125 Te SWL Mooring Wire Deployment & Recovery Winch is designed and manufactured for the mooring wire replacement of the Nan Hai Sheng Li FPSO and for installation on the vessel Haiyangshiyou 709.After studying the present designing condition of domestic winch, aiming at some disadvantages in traditional method, such as low precision, large safe factors, high cost and so on. The research focuses on applying CAD/CAE technology on the design of the winch. The research aims at providing a designing method for the similar large structure.Firstly, the project chooses Pro/Engineer software to modeling the 125 Te SWL Mooring Wire Deployment & Recovery Winch and main parts, and produces finite element models. Then the thesis uses the Pro/Engineer and the Ansys software exchange connection, importing the finite element models into the ansys software and carrying on the analysis for the finite element models. The stress and the displacement cloud charts about the whole winch and main parts are obtained.Secondly, according to the stress and the displacement cloud charts of the winch, this project carries on the improvement design and analysis for the frame structure and protrusion, meanwhile, carries on the sensitivity analysis and optimization analysis for two reel shafts. The results are satisfactory. At last, the file analyses the improved and optimized winch, the results of the analysis indicated the performance of the winch has obtained the enhancement.The research method has certain engineering practicability and wide applicability; it has some model functions to the similar large structure in the design and structure improvement. Its advantages and wide foregrounds are to be exhibited with deeper study.
