Numerical simulation of an amphibious vehicle sailing resistance
نویسندگان
چکیده
In order to evaluate the waterborne performance of amphibious vehicle, based on Fluid Dynamics and principle of marine mechanics related knowledge, the resistances and viscous flow field of amphibious vehicle in different headway were numericaly simulated by solving Navier-Stokes equatlons with the k ε − turbulence model. we obtained the result of frictiona resistance coefficient 、 residual resistance coefficient and running resistance coefficient,thus we can calculate its total resistances. the reliability of computing methed was validated by comparing the calculation results with the test data.

RANS Simulation of Viscous Flow around Hull of Multipurpose Amphibious Vehicle
The practical application of the Computational Fluid Dynamics (CFD), for predicting the flow pattern around Multipurpose Amphibious Vehicle (MAV) hull has made much progress over the last decade. Today, several of the CFD tools play an important role in the land and water going vehicle hull form design. CFD has been used for analysis of MAV hull resistance, seakeeping, maneuvering and investiga...
متن کاملSyddansk Universitet On steering a sailing ship in a wearing maneuver Jouffroy, Jerome
Compared to more conventional ships, little attention was given to nonlinear control design for ships sailing by the wind. Following our previous work, this paper addresses the issue of trajectory and reference input generation for a model that imitates the general behavior of sailing vessels. Specifically, we consider the generation of paths to perform a wearing maneuver. A feedforward control...

متن کاملA real-time recursive dynamic model for vehicle driving simulators
This paper presents the Real-Time Recursive Dynamics (RTRD) model that is developed for driving simulators. The model could be implemented in the Driving Simulator. The RTRD can also be used for off-line high-speed dynamics analysis, compared with commercial multibody dynamics codes, to speed up mechanical design process. An overview of RTRD is presented in the paper. Basic models for specific ...
