A Visual Simulation Of Submarine Variable Vector Propeller Control System

With embedded development of exploitation of ocean, Variable Vector Propeller (VVP) is produced. The VVP can produce six directional powers so the weight and bulk of submarine can be reduced. The computer simulation of the submarine under the VVP control system has significant on the research of the Variable Vector Propeller control system's research, especially under the laboratory condition's research work.The VVP's three-dimensional model was established, using three dimensional modeling software SolidWorks, based on the research of VVP's pitch control system in this article. Study of the VVP entity movement simulation was carried on the SolidWorks software platform. Combining the object-oriented organization analysis system with the SolidWorks feature modeling function, a set of three dimensional parameterization entity movement simulation system of VVP control system is established. This system has high capability of automatic calculation and analysis, and provids the comprehensive accurate data for VVP design as reference. In order to give a better demonstration of the VVP's working condition, a visual simulation system under the MFC environment using the OpenGL language is developped. It realized real-time emulation and interaction control function. Concrete work including following three parts:Firstly, using the powerful modeling function of the SolidWorks on parametric feature, part design is accomplished, assembly body design and engineering drawing of the VVP, and has realized the simulation assembly process of the VVP is realized. By adding some linear motors and revolving motors, physical movement of the VVP is simulated.Secondly, VC++ is used to re-develop SolidWorks, some basic functions of SolidWorks are realized by programming. Amining at the traversal components data function of the VVP, with the text data obtained by this function, different positions of the propelle during moving process are shown and simulation curve SolidWorks are realized by programming. Amining at the traversal components data function of the Variable Vector Propeller, with the text data obtained by this function, different positions of the propelle during moving process are shown and simulation curve generated.Finally, according to the mathematical model of the Variable Vector Propeller, a visual simulation sytem of the Variable Vector Propeller control system is developed under VC++ environment. This simulation system mainly includes initialization and planning of the terrain,planning and the navigation of the submarine, t planning and movement of he propeller, planning the watermark of the rear part of the submarine as time changes, roaming process of the viewpoint, and processing of the simulation data.
