Research On Design Of Mooring Bed Distribution And Simulation Of Mooring Loads For Ship-Based Helicopter

The wind and wave of the sea are so violent that when sailing on the sea, the ship is being in complicated surroundings. How to keep the force of riggings reasonable is a key problem. In this paper, the study is carried out on the design of mooring bed and simulation of mooring loads of the ship-based helicopter, so as to meet the demands of our national defence.The main contents and results in this paper are as follows:Firstly, the digital image processing technique is used for recognize the coordinates of the landing-points. Then, based on these coordinates, the mathematic model is built up, and the weights of effecting factors are evaluated.Secondly, the model involving helicopter, riggings and moorages are built up based on the FEA(Finite Element Analysis).Thirdly, GA(Genetic Algorithm) is used to realize the optimization of single ship-based helicopter. The optimization model and constraints are also presented. Then, the area-distribution is optimized based on the optimization of single helicopter.Lastly, new software system is developed successfully, using C++ language, Matlab, Ansys, and so on. The function of the software includes the landing-points gathering, the model building, simulation of mooring loads and optimization of the mooring bed distribution.
