【摘要】：随着国家工业化大发展时期的到来,国家能源建设投入急剧加大,建设速度迅速提升,建设能力极大增长,使得对大型起重机械吊装的需求异常旺盛,以履带吊为主的大型及特大型起重施工和以汽车吊为主的中小型起重施工行业市场应运而生。因此,使吊装作业过程和虚拟现实技术相互融合利用的仿真模拟系统的研究就变得意义非凡。首先,研究开发系统所需面向对象编程技术,在对三维软件Inventor进行了分析研究之后,利用其强大的三维建模功能,结合起重机的结构组成及工作原理后,创建了完整的起重机三维参数化模型。其次,结合实际分析起重机选型所需条件,给出了使起重机选型得以实现的程序设计方法,此方法对选型过程中的起重量、工作幅度、起升高度、臂架与被吊物的间距及接地比压等因素进行了详细的研究。最后,将本研究内容应用于三维吊装仿真的系统中,以达到辅助吊装方案制定人员对吊装过程进行仿真的目的。经由仿真,利用逼真的模型影像演示吊装作业过程,提前剔除不可行的方案。模拟结束之后输出相应的结果,使方案制定人员对各种情况进行综合比较,以寻求最佳吊装方案,以此使得吊装方案的制定效率以及方案的可靠性得到了很大的提高。
[Abstract]:With the arrival of the large-scale development of national industrialization, the investment in national energy construction has increased sharply, the construction speed has been rapidly promoted, and the construction capacity has been greatly increased, making the demand for large-scale lifting machinery extremely exuberant. The market of large-scale and super-large lifting construction and small-and medium-sized lifting construction industry mainly based on automobile crane emerged as the times require. Therefore, the research of simulation system, which makes the hoisting process and virtual reality technology merge and utilize each other, is of great significance. Firstly, the object-oriented programming technology of the system is studied. After the analysis and research of the 3D software Inventor, the powerful 3D modeling function, combined with the structure composition and working principle of the crane, is used to make use of its powerful three-dimensional modeling function. A complete 3D parametric model of crane is created. Secondly, combining with the actual analysis of the required conditions of crane type selection, the program design method to realize the crane type selection is given. This method gives the lifting weight, working amplitude and lifting height in the process of selecting the crane type, and then gives the program design method to realize the crane type selection. The distance between the jib and the suspended object and the ground specific pressure are studied in detail. Finally, this research content is applied to the three-dimensional hoisting simulation system, in order to achieve the purpose of assisting the hoisting plan-maker to simulate the hoisting process. Through the simulation, the realistic model image is used to demonstrate the lifting process, and the unfeasible scheme is eliminated in advance. After the simulation, the corresponding results are outputted, so that the scheme makers can make a comprehensive comparison of all kinds of situations in order to find the best hoisting scheme, so that the efficiency and reliability of the hoisting scheme can be greatly improved.
