[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.
