Abstract Since the beginning of the 21st century, the unmanned surface vehicle (USV) have been widely used in various fields of the ocean, and countries have conducted research on USV performance。 Compared with the United States, Israel and other countries, China in the unmanned boat hydrodynamic performance research remains to be improved, how to consider the cost of research in the context of effectively improve the efficiency of USV research is the current priority。
Different from the traditional method of hydrodynamics, this paper uses HEXPRESS to mesh and refine the unmanned surface vehicle , make the grid, and then introduce the generated mesh into FINE/Marine for numerical simulation。 According to the calculated results, the unmanned surface vehicle with the optimal resistance performance were selected and modeled。 The model was quickly tested to verify the accuracy of the numerical simulation data。The establishment of the unmanned surface vehicle integrated optimization mathematical model,the preparation of optimization procedures, performance optimization。 Specific steps are as follows:
(1) Select a unmanned surface vehicle , in its bilge at both ends of the set of different anti-splash, the bow set adjustable angle of the single pillar of the hydrofoil, and then designed a new type of unmanned surface vehicle boat to adjust the boat type parameters , Get a group of unmanned aerial model。
(2) The numerical simulation is carried out by using CFD, and the results are compared and analyzed, and the parameters of the unmanned surface vehicle , anti-splash and hydrofoil are obtained with the best resistance performance。 According to the analysis results, the model is made and the fastness test is carried out to verify the accuracy of CFD numerical simulation results。 水面高速无人艇的艇型优化设计及分析:http://www.youerw.com/zidonghua/lunwen_203398.html
