Motion visual simulation method for underwater super-cavity vehicle

Abstract

The invention provides a motion visual simulation method for an underwater super-cavity vehicle. A visual simulation system consists of a calculation module, a model loading module, a view display module and a communication module, wherein the calculation module comprises a super-cavity vehicle motion model, a stable cavity flow model, a control rule and a super-cavity vehicle trajectory model; the model loading module establishes a two-dimensional model and receives updating data and a message; the view display module receives a real-time operation instruction and carries out two-dimensionalgraphics real-time display and view re-drawing; and the communication module provides a uniform interface and acquires track calculation model data and transfers the real-time updating data to each view simultaneously. The invention provides the visual simulation system of the super-cavity vehicle which can make a user know a motion rule of the super-cavity vehicle more intuitively through simulation and can assist in finishing the design, verification, filtration and determination of a control scheme by combining the longitudinal motion control of the super-cavity vehicle and a virtual reality technology based on an open graphics library (OpenGL).

Description

technical field [0001] What the present invention relates to is a kind of simulation method, specifically a kind of visual simulation technology of supercavitation vehicle motion control system, especially combines the motion posture of supercavitation vehicle body, the formation process of cavitation, and computer graphics Visual simulation technology combined with learning. Background technique [0002] Because all or most of the body of the supercavitating vehicle is wrapped by cavitation, the fluid resistance suffered by the vehicle is significantly reduced, so its navigation speed can reach more than 100m / s. At present, the dynamics and control of supercavitating vehicles have become a research hotspot in various countries. Relevant domestic institutions and universities have realized the development prospects of supercavitating vehicles, and have started related research work one after another. China has also learned more international research trends from relevant i...

Problems solved by technology

The projectile research method is physical simulation, which can grasp the performance and motion of the control body from a macro perspective, but the cost is high, the process requirements are complicated, especially the repeatability is poor, and the risk is high

Therefore, it is difficult to obtain the dynamic characteristics and control laws of the supercavitating vehicle completely relying on experimental research.
