SIMULATION AND PREDICTION OF THE THERMALLY INDUCED DEFORMATIONS ON MACHNIE TOOLS CAUSED BY MOVING LINEAR AXIS USING THE FDEM SIMULATION APPROACH

摘要

In this study the structure of a machine tool is analyzed using the Finite Difference Element Method (FDEM) simulation approach. This approach for the computation of thermally induced displacements of machine tools structures is characterized by using finite differences for the temperature field and based on that finite elements for the thermoelastic displacements. The simulation results are verified via measurements of displacement and temperatures in a test according to ISO 230-3.
