Investigation of components and assembly groups (B03)

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

.Subproject B03 focusses the impact of components and assembly groups on the thermo-elastic behavior of a machine tool. In this context, two key objectives are being pursued. One the one hand, metrological investigations on in-house developed and operated test rigs allow analyzing and evaluating the respective thermo-elastic behavior. Here, especially the friction characteristics of active components are explored deeply. On the other hand, the previously identified behavior is simulated with FE-models.Furthermore, as integration object a motorized spindle is used to merge results from different subprojects in just one test object. Besides a metrological investigation, the development of an online-capable thermo-mechanical simulation environment is driven forward. By integrating control-internal data, a process parallel calculation of the spindle’s thermo-mechanical operation point is enabled.In the 3rd phase, components and assembly groups are analyzed in the context of a machine tool.
