【摘要】： 现在,对于高空作业车的推广展示和技术交流,主要还是依赖实物、广告宣传以及少量的3D动画等。这种产品展示,因受设备规模、场地条件等的限制,仅凭其外观是不能很好的了解高空作业车的机械性能和工作特点的。根据作者对文献的查询,目前存在的三维演示软件多局限于简单的模型演示,真正开发出实用性较强的演示软件国内仍比较少见,国内目前尚不存在针对高空作业车工况演示,技术特性计算和计算结果显示功能相结合的成熟三维软件,因此对高空作业车虚拟运动系统的研究有着重要的意义。本文针对以上问题,以GTBZ系列自行式高空作业车为研究对象,着重研究了组件对象模型技术、面向对象的几何建模方法以及高空作业车的运动仿真技术,实现了GTBZ系列高空作业车的三维模型建立、基本工况仿真和对技术特性参数的实时显示,通过人机交互,实现相应技术特性参数的计算,如稳定性和轮胎支反力等。本文研究的核心技术有以下几点: 组件对象模型技术是虚拟运动系统的核心研究内容之一,本文设计了与Matlab联合仿真的底层接口,实现了对Matlab的循环调用来显示不同工况下各技术参数。面向对象的几何建模方法是虚拟运动系统中的另一核心研究内容。本文深入研究了基于OpenGL的图形学方法,创建符合高空作业车结构的基本几何体,给出了虚拟系统中三维建模原则和实现方法。运动仿真技术的研究是结合图形变换的基本知识和高空作业车的运动特点,给出了高空作业车虚拟运动系统的运动计算模型建立方法,实现了高空作业车的仿真运动。最后将上述核心研究内容相结合,在Visual C++.Net开发平台下,实现了一个基于OpenGL的自行式高空作业车虚拟运动系统,对该系统进行框架设计并给出系统的实现效果,验证了前几项技术的可实现性。
[Abstract]:At present, the promotion of aerial vehicle display and technical exchanges, mainly rely on physical objects, advertising and a small amount of 3D animation. Due to the limitation of equipment scale and site condition, the mechanical properties and working characteristics of aerial work vehicle can not be well understood by its appearance alone. According to the author's inquiry to the literature, most of the existing 3D demonstration software is limited to simple model demonstration, and the development of practical demonstration software is still relatively rare in China. At present, there is no demonstration for the operating condition of aerial vehicle in China. Because of the mature 3D software which combines the function of technical characteristic calculation and the result of calculation, it is of great significance to study the virtual motion system of aerial vehicle. In order to solve the above problems, this paper takes GTBZ series self-propelled aerial vehicle as the research object, focuses on the component object model technology, the object-oriented geometric modeling method and the motion simulation technology of the aerial vehicle. The 3D model of GTBZ aerial vehicle is established, the simulation of basic working condition and the real-time display of technical characteristic parameters are realized. Through man-machine interaction, the calculation of corresponding technical characteristic parameters, such as stability and tire support reaction force, is realized. The key technologies of this paper are as follows: component object model technology is one of the core research contents of virtual motion system. In this paper, the bottom interface of joint simulation with Matlab is designed. The circular call of Matlab is realized to display the technical parameters under different working conditions. Object-oriented geometric modeling method is another core research content in virtual motion system. In this paper, the graphic method based on OpenGL is deeply studied, and the basic geometry which accords with the structure of aerial vehicle is created, and the principle and realization method of 3D modeling in virtual system are given. The research of motion simulation technology is based on the basic knowledge of graphic transformation and the motion characteristics of aerial work vehicle. The method of establishing motion calculation model of aerial work vehicle virtual motion system is given, and the simulation motion of aerial work vehicle is realized. Finally, a virtual motion system of self-propelled aerial vehicle based on OpenGL is implemented based on Visual C. net, and the frame of the system is designed and the effect of the system is given. The realizability of the former techniques is verified.
