一种大型复杂异形钢构件的偏差分析及工厂修正指导方法
摘要：
本发明公开了一种大型复杂异形钢构件的偏差分析及工厂修正指导方法，基于综合技术计算机技术、逆向成形、虚拟现实、三维扫描技术）对大型复杂异形钢构件的偏差进行分析和修正，包括以下步骤：创建钢构件Tekla模型；制作钢构件；制作钢构件可视化的三维坐标系；逆向生成的三维Test模型；将Tekla的模型转换为第三方的Reference模型；制作三维偏差色差图；并对偏差部位进行任意面的剖切，制作二维视图偏差分析图；对偏差的钢构件进行修整。本发明将现场安装存在的问题提前消化在工厂之中，大幅提高现场安装的效率，缩短安装工期，从而提高整体进度。
摘要（英）：

The invention relates to a deviation analysis and factory correction guiding method of a large-scale complicated special-shaped steel component. According to the method, the deviation of the large-scale complicated special-shaped steel component is analyzed and corrected based on comprehensive technologies such as computer technology, reverse forming, virtual reality and three-dimensional scanning technology. The method comprises the following steps that: the Tekla model of the steel component is created; the steel component is fabricated; the visualized three-dimensional coordinate system of the steel component is fabricated; a three-dimensional test model is reversely generated; the Tekla model is converted into the reference model of a third-party; a three-dimensional deviation color-differentiated chart is fabricated; arbitrary plane cutting is carried out on a deviation portion, a two-dimensional view deviation analysis chart is fabricated; and the deviated steel component is trimmed. With the method of the invention adopted, problems existing in field installation can be solved in a factory in advance, and thus, the efficiency of field installation can be greatly improved, an installation period can be shortened, and an overall progress can be accelerated.
