| Abstract: | By focusing on the steel truss beam,the basic principle of virtual pre-assembly was analyzed,as well as the virtual assembly process,the key elements such as the creation of theoretical model,selection of measuring points,measurement accuracy and temperature influence were also included.The virtual preassembly system was built,which includes two modules,precision management and assembly management.Taking a practical bridge project as an example,the comparison and analysis of the traditional way and the virtual pre-assembly were carried out,and the results are in good agreement with each other,which shows the feasibility and accuracy of the virtual pre-assembly technology.The study provides a useful reference for the application and extension of the virtual pre-assembly technology for steel truss girder. |
