英文摘要：

The hardware structure of the digital multiple UUVs simulate platform and the flow of hydrodynamic calculation of single UUV and multiple UUVs are introduced, and based on these analyses, the hydrodynamic calculation is implemented for multiple UUVs using Windows multithreads technology. This method has been apphed in the digital multiple UUVs simulate platform for virtual environment node design and has been well validated. The system simulation experiment has shown that the program has good efficiency of execution and real-time response ability which is designed by this method, and established the foundation for hydredynamic calculation for bat-physical multiple UUVs simulate platform and for validation of hydrodynamic efficiency in real multiple UUVs system in the future.
