Abstract
This study pertains to the application of system equivalent model mixing to an experimental and analytical model. System equivalent model mixing is applied to a suspension subframe model, and virtual points at the suspension mount points are set as target points. Subsequently, the six degree-of-freedom frequency response functions at the virtual points are predicted. To improve the accuracy of dynamic characteristic prediction at the target points, system equivalent model mixing with extended compatibility is applied. Points in the test or analysis that can be used to apply system equivalent model mixing are not limited. The accuracy of the system equivalent model mixing is analyzed based on changes in the points in the analysis and test model. The mixing points for the system equivalent model are optimized via preliminary analysis in the pre-test stage.
