摘要
Abstract
The underwater towed body is an important component of underwater vehicles.For the requirements such as the design of the towing cable for underwater towed bodies and stable attitude during the release process,this paper constructed the fluid dynamics model of the towed body by the overlapping mesh technology and the achievable k-ε turbulence model.It also carried out the unsteady numerical simulation of the release process.After the simulation,the paper verified the effectiveness of the grid division and numerical methods through the experimental results.The paper systematically analyzed the influence of towing speed,the position of the barycenter and the buoyant center,and the towing point on the release process of the underwater towed body.The simulation results show that towing speed affects the stabilization time and attitude stabilization process of the towed body,and the optimal towing speed needs to be determined according to the structure of the towed body.The positions of the barycenter and the buoyant center have a significant effect on the release dynamic characteristics of the towed body,and the design of moving the barycenter forward can reduce the oscillation of the towed body and improve the stability of the system.When the barycenter is close to the buoyant center,the attitude adjustment time of the towed body is shorter,and the movement is more stable.The towing point should be under the head of the towed body to reduce the change in pitch angle during the release process and improve the stability of the release process.The results provide an important theoretical basis for the engineering design and release strategy of underwater towed bodies.关键词
