Research on the modeling and simulation technology of underwater vehicle

Underwater vehicle is an important tool in the exploration, survey and investigation of the ocean and have many scientific, military, and commercial applications. To develop an underwater vehicle is not an easy task; a reliable underwater vehicle requires a thorough system design and many costly field tests during which system specifications can be validated, and these field tests can be hard and time-consuming. In the development of underwater vehicles, modeling and simulation technology can provides a cost-effective measure to carry out preliminary components, system, and mission testing of the vehicle, thereby reducing the number of potential failures in field tests. This paper first give a review of the simulation technology of underwater vehicles, then a simulation system of an autonomous underwater vehicle and a simulation system of a human occupied vehicle was described respectively; finally, a new type of simulation system of underwater vehicles was introduced.
