Zhang, S.; Sun, L.; Yang, T.; Song, S., and Xu, K., 2018. Resistance appearance design of deep-sea vehicle under complex seabed terrain. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 324–327. Coconut Creek (Florida), ISSN 0749-0208.

In this research, a resistance appearance of modular deep-sea vehicle has been designed, which has the basic navigation ability and can extend other functions. Using the 3D design software Solidworks and the computational fluid dynamics software CFX, the appearance is optimized to reduce the appearance power of the deep-sea vehicle. The connection form of each function module and between the cabins are made modular design, to make the structure more simple, convenient replacement and maintenance; In addition, the theoretical calculation and software simulation for the strength and stability of the pressure resistant shell are also carried out. The experiment proved that the design of the appearance of the deep-sea vehicle using sensor onboard navigation can complete the basic functions, including Autonomous directional navigation, autonomous constant speed navigation, autonomous constant depth navigation and position closed-loop navigation function, of which the cost is low, greatly reducing the workload.
