水陆两栖车辆水上运动特性实时仿真系统研究

A real-time simulation system for the hydrodynamic characteristics of amphibious vehicles is designed to solve the problems of dificultly acquiring the hydrodynamic parameters and slowly predicting the motion attitude of amphibious vehicles. It can realize the driving of simulation models, motion attitude prediction, data monitoring and output. The numerical calculation method(CFD) is used to correct the vehicle dynamics coefficients, which significantly improves the accuracy of real-time simulation system. In addition, a test amphibious vehicle is developed to verify the accuracy of real-time simulation system under different working conditions. The results show that the real-time simulation system can be used to accurately and efficiently simulate the hydrodynamic characteristics of amphibious vehicles, and predict the motion attitude of the vehicle quickly and accurately. It is also applicable to various complex working conditions and has universal applicability for attitude prediction. The system has strong application value and application prospect in the development stage of amphibious vehicles, driver training, semi-physical simulation exercises and complex environment simulation.
