Visualization method for multi-model stress comparative analysis and related equipment

Abstract

The embodiment of the invention provides a visualization method for multi-model stress comparative analysis and related equipment, and belongs to the field of stress analysis and the field of data visualization. The method comprises the steps of obtaining a design scheme; converting the node stress data into stress body data; automatically grouping voxels with similar stress modes in different design schemes according to stress body data; performing tree view display: adopting hierarchical tree layout, organizing a plurality of schemes generated in an iterative design process, and providing volume rendering based on a stress value or a stress difference value; and performing comparison view display: arranging voxel groups obtained by segmentation according to rows by adopting matrix layout, arranging different design schemes according to columns, and simultaneously realizing stress comparison analysis among multiple schemes and local stress analysis in a single scheme through visual comparison among rows and columns. According to the method, the stress mode or the stress difference mode in the design scheme is extracted, the overall stress mode and the local stress mode are considered, and engineers are helped to better execute decisions.
