摘要

This paper presents a comparison of three different methods of simulating heat sources in 3D-FEM-simulations with various levels of abstraction for drilling. The investigated methods are modelled and evaluated with respect to calculation time and accuracy of simulated temperature fields and phase transformations. Results are showing a significant variance of the maximum temperature and temperature distribution for the three different heat sources although the same amount of energy is used in the simulation model. According to the longest simulation time the most detailed heat source provides a realistic temperature distribution.
