Identification of exemplary scattering and time-varying thermal model parameters (B04)

• Subject Area: Engineering Design, Machine Elements, Product Development ; Mechanics
• Term: from 2011 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 174223256

B04 develops methods and tools for an efficient parameter adjustment support. One focus is the planning of the adjustment during the commissioning phase. Therefore, uncertainty analyses for the determination of parameters to be adjusted as well as the design of load regimes for parameter stimulation, which are compressed in time and parallelized for the axis assemblies of the machines, are performed. The second focus is the adjustment of time-varying parameters in the operating phase. For this purpose, measurement values, measurement locations and measurement times are analysed and methods of stimulation detection and model error evaluation are investigated for suitability. Subsequently, methods for economic measurement will be developed primarily based on control data.
