Intelligent design system and method for sheet metal sculpture profile steel frame

Abstract

The invention discloses an intelligent design system for a sheet metal sculpture profile steel frame. Based on a CAD design platform, firstly a design reference surface is established according to an arrangement rule of the profile steel frame based on a profile curved surface of a sheet metal sculpture; the design reference surface is crossed with the profile curved surface to obtain a design feature curve of the profile steel frame; the feature curve of the profile steel frame is processed to obtain a main curve of the feature curve; the feature curve is converted into multiple line segments by adopting an interpolation method; interface design of the profile steel frame is finished by adopting a curve offset method; physical model design of the profile steel frame is finished by adopting a tensile modeling method; according to the arrangement rule of the profile steel frame, cross section graph design of a matching groove of the profile steel frame is carried out; cutoff design of the matching groove is finished; interference checking is performed by adopting a virtual assembling method; an uncompleted matching groove cutoff position is checked; interference part processing is finished; and finally the design of the profile steel frame is finished. The design speed can be effectively increased and the design workload of designers is greatly reduced.

Description

Technical field [0001] The invention relates to an intelligent design system and design method technology for a sheet metal sculpture profile steel frame, and belongs to the technical field of intelligence and automation. Background technique [0002] The sheet metal sculpture building can be considered as composed of three parts as a whole. The first part is the complex surface, which is the exquisite appearance of the sculpture that people see; the second part is the surface steel frame attached to the complex surface. The modeling function also has the function of the surface and curved surface to strengthen the ribs; the third part is the load-bearing steel frame, which is the main bearing component of the sculpture. In the design of sheet metal sculptures, the design of the profile steel frame is the most complicated. In order to ensure the correct cooperation of the profile steel frame, as well as the installation of the profile steel frame with the sculpture profile and th...

Problems solved by technology

[0003] At present, the traditional design method of large-scale sheet metal sculpture-shaped steel frame has great limitations, and it completely relies on the designer for drawing operations. This design method has low work efficiency and takes up a lot of human resources. The design speed depends on the designer's proficiency degree, and it is easy to make mistakes in the design process, which seriously restricts the production efficiency
