Model Description

■ 8421 BK Connect Correlation Analysis This application generally allows two modal models of the experimental model limited element (FE) model to perform a total of visual comparison and numbers comparison. The complete workflow process is intuitive and flexible, supports geometorian lines, flexible (DOF) mapping, comparison, mode pairing, and reporting. In addition, you can use the test plan and test verification tools to design the optimal test conditions to evaluate different modeling strategies. ■ Functional ・ Import of experimental modal model in standard format ・ Import FE models such as NASTRAN® (MSC, NX, NEI), ANSYS®, ABAQUS® or UFF files ・ Select and verify the experimental node from the FE model for the test plan ・ Desimation of a finite element model for creating a test model (retreat) ・ Execute DOF mapping so that DOF matches from two correlated models Calculation of Automac, Crossmac, self -orthetic table, orthogonal, and 3D plot in the reduced test space ・ Imported matrix matrix from NASTRAN or ABAQUS ・ If the shrinking mass matrix is ​​not available, you can use Serep algorithm ・ Expansion of experimental modal vector to FE space using Serep algorithm ・ Integrated Microsoft® Office Report Function ■ Comparison tool With this software, you can easily compare the alignment and match the scales and coordinates of the two geometric models. You can animate various tests and FE mode shape, display mode tables, and clearly compare modal parameters. Depending on the degree of frequency correlation or shape correlation, mode pairing can be automatically paired from two modal models.
