摘要
针对大型钢结构吊装施工困难,易发生碰撞损伤、安全稳定性失效等问题,提出了一种虚拟吊装技术来实现对钢结构吊装施工全过程的模拟。基于Arc Objcts开发,采用二维、三维联动技术对建筑外观场景进行二维和三维联合仿真,通过特定视角选取作业空间,避免钢构件吊装过程中出现碰撞等安全事故。同时将虚拟吊装模型与ANSYS分析软件结合,对吊装构件和设备的应力状态和变形进行分析,以满足钢结构吊装过程中的安全稳定性要求。通过实例对开发的大型钢结构虚拟吊装施工系统进行了验证,结果表明:开发的虚拟吊装施工系统能实现对吊装现场实时漫游监控,避免了因施工顺序混乱而造成的钢构件无法安装或高空待装构件发生碰撞损伤等问题,通过软件对钢构件的位移、应力和安全稳定性指标进行分析,保证了钢结构吊装施工的安全。
In order to solve the problems in hoisting construction of large steel structures, such as easy to collision damage, safety and stability failure, a virtual hoisting technique was proposed to simulate the whole process of steel structure hoisting construction. Based on the development of Arc Objcts, the two-dimensional and three-dimensional linkage technology was used to simulate building exterior scene 2D and 3D joint, and the working space was selected by a specific angle to avoid collisions and other safety accidents during the lifting process of steel components. At the same time, using virtual hoisting model and ANSYS analysis software, the stress state and deformation of the hoisting members and equipments were analyzed to meet the requirements of security stability of the hoisting process of steel structure. The large steel structure virtual hoisting construction system developed by the examples was verified. The results showed that the developed virtual hoisting construction system could realize the real-time roaming monitoring of the hoisting site, it could avoid the problems that steel components could not be installed due to chaotic construction sequence or collision damage at high altitude. The software was used to analyze the displacement, stress and safety stability of steel members, so as to ensure the safety management of steel structure hoisting construction.
