In order to improve the speed of amphibious vehicle drive in the water,the article proposed that using Combined Modeling method in UG to build multi-regional and multi-shape model from considering the resistance of amphibious vehicle;then we combined with the computation speed and accuracy,using HyperWorks software to mesh the units of the model;also we designed that in different driving conditions,using hydrodynamics analysis software to get the model's simulation analysis results;at last we do a simulation of viscous flow round of amphibious vehicle by using k-e two-equation turbulent model.The results show that: the shape of bodywork tail and the outstretched wheel both have great influence on the viscous flow field;and the vehicle driving parts position's change can reduce the resistance of the vehicle driving in water;meanwhile the article proved that the drive environment change also has much more effect on resistance of vehicle driving in water.Finally the experimental data was given which proved the above conclusion,also these experimental data can be provided as a reference for the designer who want to design and analysis bodywork in the future.
