摘要
以车辆的振动模型为例,探讨了结合MATLAB软件和虚拟现实编程语言在振动问题中的应用.将车辆简化为在铅直平面内的两自由度模型,通过虚拟现实编程语言创建模型构件的三维模型,并与MATLAB的仿真工具包Simulink接口.建立了仿真模型,并得到了仿真模型在给定的初始条件下的响应,以动画的形式直观地表达出来.虚拟现实技术的应用,使得抽象的振动问题和数学公式变成直观的运动,其仿真结果符合结构的振动规律,表明虚拟现实技术对于振动问题的仿真是可行的.
The application of MATLAB and Virtual Reality Modeling Language（VRML） in vibration problems was researched.The vibration modal of vehicle was used as an example.The vehicle was idealized into a two-degree vibration model.The three-dimensional body was established by VRML and interfaced with Simulink.The response of the vibration system was obtained under the original conditions with the form of animation.The application of virtual reality technology changes abstract vibration problems and mathematical formulas into intuitionistic movement.The simulation results conform to the law of vibration.It is indicated that the virtual reality technology for vibration problems is a feasible simulation methods.
