Background
- FEM-analysis is used to determine natural frequencies of a frequency converters and evaluate their behaviour and mechanical strength in vibration tests.
- One of the main challenges currently is how to model contacts between components for linear FEM-analysis (modal analysis and vibration response analysis) accurately enough.
Target
- To have contacts modelling technique for linear FEM-analysis, which could be applied for modelling accurately FEM models of large assemblies. It must be possible to utilize developed techique(s) in main commercial FEM softwares ( Abaqus, Ansys etc.)
- Real-life reference testing of analyzed objects is needed to verify the accuracy of developed modelling method.
