Transport Hose In Deep-sea Mining System Parameter Optimization

Deep-sea Mining is the advance guard of the high technology in Ocean . The pipe is a very important section of the Deep Seabed Mining System. Only a pipe which is designed properly can ensure the system all can work very well.To reach this target, we analyze "the Large Distortion "of the pipe many times in a lot of different conditions. We research how the parameters effect the load of both sides of the pipe and the shape when the pipe distorting.So the results of the research offer some direct conclusion in theory and lay a foundantation for simplifying the optimization model.On the basis of that, we built two kinds of optimization model.One is a model include two decision variables and two objective functions;the other is a a model include two decision variables and one objective function.In the latter ,the rate of the restortion of the pipe is the constraint.Using the two models,we solve some problems in the project and get results that can be regarded as reliable reference data.
