Embodiment 1

[0052] like figure 1 As shown, the present invention provides a method for automatically adjusting the included angle of steel sections based on three-dimensional coordinates, including:

[0053] S10: Obtain the three-dimensional coordinate information, load point information, and pipeline information of the steel to be adjusted, and establish an overall coordinate system for the steel shape based on the three-dimensional coordinate information, load point information, and pipeline information.

[0054] Specifically, the load points on the brackets of different hanger types are different. In this embodiment, the hangers are in the vertical direction, and the points of the bracket points on the pipeline projected onto the bracket steel in the vertical direction are the load points on the steel.

[0055] When the load point is not specified, the starting point of the first section steel is taken as the origin of the coordinate system, the direction of the section steel itself is...

Abstract

The invention discloses a steel section included angle automatic adjustment method and device based on three-dimensional coordinates. The method comprises the following steps:establishing a profile steel overall coordinate system based on three-dimensional coordinate information, load point information and pipeline information of profile steel; generating a profile steel local coordinate system based on the orientation of the to-be-adjusted profile steel in the profile steel overall coordinate system; obtaining the section shape of the to-be-adjusted profile steel, and obtaining a profile steel section local coordinate system according to the section shape of the to-be-adjusted profile steel; comparing the difference between the profile steel local coordinate system and the profile steel section local coordinate system, and calculating the section included angle of the to-be-adjusted profile steel by adopting a mixed product principle; and generating a steel structure analysis software command stream based on the section included angle, wherein the steel structure analysis software command stream is used for adjusting the section included angle of the to-be-adjusted profile steel. The absolute consistency and accuracy of a design model and a mechanical model are guaranteed, and the efficiency and accuracy of steel structure mechanical analysis are improved.

Description

technical field [0001] The invention relates to the technical field of reactor structural mechanics analysis, in particular to a method and device for automatically adjusting the included angle of a steel section based on three-dimensional coordinates. Background technique [0002] In engineering design software (such as PDMS, SP3D design system), the information of the steel structure is constructed by the coordinate information of the starting node, the coordinate information of the ending node, and the coordinate information of the key nodes of the section. The information of the steel structure section and the user-defined way related. In the steel structure analysis software (GTSTRUDL), the local coordinate system of the component is defined by defining the local X-axis, Y-axis and Z-axis of the construction. A straight line, the Y axis and the Z axis are the cross-sectional principal axes of the member. In GTSTRUDL, the value of the moment of inertia of the member is ...
