Research On Visual Simulation Of Virtual Tank Movement Based On Unity3D

The research on visualization simulation of tank mobility is one of the basic tasks for constructing virtual battlefield environment.As a virtual engine tool,Unity3D has a friendly development interface,a powerful physical simulation module,and realistic real-time rendering functions,which provide convenient conditions for the visualization and simulation of tank mobility.Aiming at the shortcomings of the traditional tank virtual driving system in terms of realism,compatibility and cross-platform,this paper proposes a virtual tank movement visualization simulation system based on Unity3D.Firstly,based on the force analysis of the different movement conditions of the tank,the thesis builds the dynamic model of the tank when the tank is running in a straight line and when the tank is turning,and through the analysis of the tank transmission system,discusses the working conditions of the engine,brakes and other devices,and establishes a Mathematical model of tank transmission system;secondly,use 3Ds Max three-dimensional modeling software to build tank vehicle model and scene-related entity model,and then use Unity3D virtual engine to build the established entity model in an orderly manner,and use terrain rendering technology,sky box Technology,weather management system,etc.have built a realistic and diverse tank virtual visualization simulation scene.Using the C# script of Visual Studio and the collider in the Unity3D virtual engine,the control program script that meets the system requirements is designed,so that the tank can realize dynamic simulation in a variety of different real scenes.Then,the real-time speed and pose state of the tank vehicle dynamics model in Simulink is transmitted to the Unity3D virtual scene through the UDP transmission protocol,and the road surface information and important information of the scene in the Unity3D scene are transmitted to Simulink,realizing the integration of the two software.communication connection between.Finally,the virtual tank motion visualization cosimulation results show that the position and attitude of the virtual tank in Unity3D can be changed according to the simulation results of the mathematical model of the tank in Simulink.Based on Unity3D virtual tank movement visualization simulation research,the tank can recognize the surrounding environment and simulate the basic dynamic behavior of the tank in the virtual environment,which can lay the foundation for the follow-up research on the intelligent driving technology of the tank.
