The Launching And Retrieve Simulation Of Deep Submergence Vehicle Based On The Virtual Reality Technology

With the over exploitation of land resources,people urgently need to find a suitable replacement resources,deep sea resources have gradually become an important strategic goal for each country which contains abundant polymetallic nodules?deep-sea oil?deep-sea biological gene and other resources.Deep-diving technology is a necessary means for marine development,the training for submerged member and scientists are using the real boat currently.Due to high demands for the environment?high cost?long period and high risk by using the real submarine training,so the development of virtual training system related with submersible has important strategic significance to meet the demand of personnel training and science education.This thesis is mainly develop the jiaolong launching and retrieve operating simulation system based on the virtual reality technology.First,investigate the jiaolong launching and recovery process,clear the laying down process of submersible;Secondly,research the development status of virtual training system at domestic and foreign,determine the final development platform according to the actual needs of the project;this system has function of interactive operation and demonstration,need to design appropriate interaction and animation trigger mechanism,so that realize the virtual human operate animation when operating;this system uses virtual reality helmet,to enhance the system's sense of immersion.The following main works has been finished in this thesis:(1)According to the traditional mass-spring model of flexible rope modeling method,the improved structure-bending spring model and the winding algorithm of rope on the roller are put forward,and simulated the winding process of ropes;(2)Using 3ds Max created 3D model of the jiaolong?support mother ship and virtual human,optimizing?UV layout and rendering the model,and making the key frame animation of virtual human,complete the creation of the model;(3)Realized the simulation of jiaolong launching and recovery process,including the key steps of flexible ropes simulation?A-frame swing and virtual human action,introduced the virtual reality helmet,realized the man-machine interaction mode based on the helmet and completed immersive visual output.
