Embodiment 1

[0029] Example 1: Refer to the attached Figure 1~3. The computer simulation assembly method of steel structure components is to perform three-dimensional measurement of the components that have been manufactured, use the measurement data to construct the component model in the computer, simulate the assembly of the component model in the computer, perform assembly interference check on the computer, analyze the assembly accuracy, Obtain the information needed for the processing of component connectors: (1) Measuring system: use one or several digital photogrammetric instruments to perform three-dimensional measurement of the measured component, the end face size, edge, and hole group of the component, and the laser tracking measuring instrument realizes The measurement of the relationship between the local groups measured by the digital camera measuring instrument, and the coordinate conversion calculation of the above two measurement data, and finally realize the three-dimensiona...

Abstract

The invention relates to a steel structural component computer simulation installment method, comprising: processing three-dimension measurement on a produced component, using the measurement data to establish a component model in computer; processing simulation installment on the component model in computer; processing installment interference check in computer; analyzing installment accuracy in computer; and obtaining the information required in the manufacture of component connectors in computer. The simulation installment of component comprises two ways, wherein one way comprises: according to the preassembly drawing requirement of the component, preassembling the established component model in a computer according to the theory positions of the drawing requirement; checking the connection relationship among the components with the product technique requirements, and feeding back the check result and the information demanded in following processes; and the second way comprises: confirming that under the support condition as the components will not deform over technical allowance under gravity, using the connection between components as rule, processing simulation preassembly on the established component model in computer, comparing the error between the assembly positions and the theory positions of the components with allowance range, and feeding back check result as preassembly adjustment and the adjustment information of following processes.

Description

Technical field [0001] The invention relates to a computer simulated assembling method of steel structure components, belonging to the manufacturing field of computer simulated steel structure component assembling methods. Background technique [0002] At present, in the field of steel structure product manufacturing, in order to ensure the smooth assembly of steel structure components into components, it is generally necessary to actually pre-assemble them according to the assembly requirements after the components are manufactured, and complete the preparation of the connectors between the components. The actual pre-assembly operation has low efficiency, high cost, high labor intensity, and certain hidden dangers of operation safety. Summary of the invention [0003] The purpose of the present invention is: in the steel structure product manufacturing process, the computer is used to simulate the assembly of the finished components, instead of the traditional actual pre-assemb...
