Title
Modeling Approaches For Controller Design Using The Example Of A Valve-Driven Force-Controlled Bearing Preload Element
Abstract
Conventional machine tool spindles are factory-equipped with a fixed bearing preload. Depending on the preload level, the field of application of a machine tool is limited to certain processing tasks. As part of a collaborative project between ICM e.V., Spindel- und Lagerungstechnik Fraureuth GmbH and SITEC Automation GmbH, funded by the European funding initiative EFRE, a novel adaptronic machine tool spindle has been developed. The new spindle offers the possibility of a variable adjustment of the bearing preload, whereby the machining spectrum of the machine tool can be significantly expanded. The functional principle is a rotationally symmetrical hydraulic bearing preload element integrated in the main spindle. By changing the pressure in the oil filled preload element, a relative displacement of the bearing rings is caused. The bearing preload can be varied proportionally to the relative bearing stroke. Aim of the investigation was to compare different levels of detail in modeling the main system components and the overall control system for the purpose of controller development. Therefor the Modelica-based simulation environment SimulationX (R) was used.
