【摘要】：作为一种高效的现代化路面养护设备，沥青路面铣刨机在公路养护方面发挥着不可替代的作用。运用虚拟现实技术对沥青路面铣刨机及其他类型的工程机械进行仿真，模拟其作业过程，研究相关参数的变化规律，是一种现代化的优化设计方法，这对降低机械产品的开发成本、缩短开发周期以及提高产品设计质量具有重要意义。 本文以沥青路面铣刨机的工作装置——铣刨转子为研究对象，首先对其作业仿真系统进行目标分析，确定了系统开发工具和实现方案，明确了系统的开发流程。然后利用专业机械设计软件SolidWorks和视景仿真建模软件Multigen Creator的相关建模技术联合构造了铣刨转子、树木等模型，利用软件开发平台Visual Studio2005与图形开发库OpenGL实现了沥青路面的离散化模型的显示，完成了仿真系统的三维场景的构建。通过实时三维虚拟现实开发工具Vega Prime的用户配置界面工具LynX Prime及其API函数创建了仿真系统的实时应用程序，利用其扩展模块Vortex for Vega Prime实现了柱状包围盒碰撞检测；结合Visual Studio2005，，采用MFC设计了仿真系统的界面部分，并进行了仿真动画的录制。 本文开发的仿真系统中的虚拟场景具有良好的真实感，能够较为真实地模拟铣刨转子的铣刨作业过程。该系统可应用于不同参数的铣刨转子的作业仿真，便于铣刨转子的设计与优化；用户通过输入不同的沥青路面参数，可以研究铣刨刀具对沥青混合料的破坏机理；系统提供的仿真结果，可以为用户选择合适的运动学参数和动力学参数、提高铣刨机的作业性能提供直观的参考。本文探寻的基于虚拟现实技术的视景仿真方法可动态再现铣刨作业过程，对其他类型工程机械的设计与研究具有一定的参考价值。
[Abstract]:As an efficient modern pavement maintenance equipment, asphalt pavement milling machine plays an irreplaceable role in highway maintenance. It is a modern optimization design method to use virtual reality technology to simulate the asphalt pavement milling machine and other kinds of construction machinery, to simulate its working process, to study the law of the change of the related parameters, and to use the virtual reality technology to simulate the asphalt pavement milling machine and other kinds of construction machinery. It is of great significance to reduce the development cost, shorten the development cycle and improve the design quality of mechanical products. In this paper, the working device of the asphalt pavement milling machine, the milling and planing rotor, is taken as the research object. Firstly, the target analysis of the operation simulation system is carried out, and the system development tools and realization scheme are determined, and the development process of the system is clarified. Then using the related modeling technology of the professional mechanical design software SolidWorks and the visual simulation modeling software Multigen Creator, the milling and planing rotors, trees and other models are constructed. The display of the discrete model of asphalt pavement is realized by using the software development platform Visual Studio2005 and the graphic development library OpenGL, and the 3D scene of the simulation system is constructed. The real-time application program of the simulation system is created by the user configuration tool LynX Prime and its API function of the real-time 3D virtual reality development tool Vega Prime. The cylindrical bounding box collision detection is realized by its extended module Vortex for Vega Prime. The interface part of the simulation system is designed by using MFC with Visual Studio2005, and the simulation animation is recorded. The virtual scene in the simulation system developed in this paper has a good sense of reality and can simulate the milling process of the planing rotor. The system can be applied to the operation simulation of milling rotors with different parameters, which is convenient for the design and optimization of milling planing rotors, and the failure mechanism of milling tools on asphalt mixture can be studied by inputting different asphalt pavement parameters. The simulation results provided by the system can provide an intuitive reference for the user to select appropriate kinematic and dynamic parameters and to improve the performance of the milling machine. The visual simulation method based on virtual reality technology, which can dynamically reproduce the process of milling and planing, has certain reference value for the design and research of other types of construction machinery.
