Research on Wave Load Calculation Method for Underwater Vehicles in Irregular Waves
摘要
Abstract
This paper focuses on the issue of wave load calculation for underwater vehicles in irregular waves.Based on three-dimensional boundary element method,and considering the influence of finite water depth,the wave load characteristics under different speed,depth,and sea state conditions are studied.Firstly,a three-dimensional boundary element model for underwater vehicle wave load calculation is established.Then,the velocity potential is calculated by numerical integration method,and the time history data of wave loads and moments acting on the vehicle in irregular waves are obtained by impulse response function approach.Furthermore,the effectiveness of this method is verified by model test results.Finally,the time history data of wave loads under various operating conditions are analyzed.The results indicate that increasing the navigation depth can significantly reduce the wave loads,while adverse sea states can lead to a significant increase in wave loads.The three-dimensional boundary element method based numerical calculation method proposed in this paper can effectively predict the wave load characteristics of underwater vehicles under different conditions.The results provides important theoretical support and practical application value for optimizing the design and control of underwater vehicles.关键词
