Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: most commercial finite element analysis softwares use line and surface structures instead when establishing the finite element model of the plate-beam structure; display as solid model
[0004] The difficulty and significance of solving the above technical problems: domestic research on graphics software systems started relatively late, and there is no specific and clear visualization method for the plate and girder structure model

specific Embodiment

[0110] Taking a hexagonal truss antenna model as an example, the line-surface model of the hexagonal truss displayed by this method is as follows: Figure 6 As shown, the solid model is as Figure 7 shown. The specific implementation steps in conjunction with the accompanying drawings of the description are as follows:

[0111] Step 1: The information of the truss antenna model is as follows: figure 2 Formatting is stored in text documents. Information includes point information and unit information. The unit only contains beam beam unit and beam section information.

[0112] Step 2: Create a single-document application. The main generated classes are document class CvtkSDIDoc, view class CvtkSDIView, and frame class CMainFrame. Objects of vtkPoints, vtkCellArray, and vtkUnstructured classes, as well as cell type arrays int*type and int*S_M_type are defined in the document class CvtkSDIDoc. Define objects of vtkRender and vtkMFCWindow in the view class, / * define points...

Abstract

The invention belongs to the technical field of computer aided design, and discloses a visualization system and a method of a truss antenna based on VTK, and a terminal. The method comprises a singledocument visualization interface application program for displaying a three-dimensional model of a plate beam structure is established. The designed file format stores the finite element model information of the beam-shell structure. Finite element model information into the design of a single document display program data structure; Calculating the coordinates of other points on the two sectionsin the beam structural element; Calculating coordinates of other points of the shell element with thickness; Create all solid elements of the plate-beam model; According to all the solid element information of the plate-beam model, the data set in VTK is created, and the visualization pipeline of graphics display is built. The VTK rendering engine pipeline is established to visualize the 3D solidmodel generated by the VTK pipeline. The invention adopts the object-oriented programming idea and has good expansibility.

Description

technical field [0001] The invention belongs to the technical field of computer-aided design, and in particular relates to a visualization system, method and terminal of a VTK-based truss antenna. Background technique [0002] At present, the commonly used existing technologies in the industry are as follows: In the field of computer-aided analysis, after years of development abroad, many commercial software have appeared on the market, such as ANSYS, Abqus and other widely used finite element commercial analysis software. At present, the country is still in its infancy. Excellent finite element analysis software In addition to accurate analysis of the model, accurate display of the finite element model can improve software interactivity. In the CAE field of mechanical engineering, many structures can be modeled using plate and beam structures; it is of universal significance to understand the visualization of plate and beam structure models. Most of the commercial finite ...
