The need of reliable structural properties of machine tools in the development phase are becoming increasingly important due
to mounting accuracy demands and shrinking development periods. The finite element method is the most established tool applied
in this context. Currently, calculating thermal properties and compensation of thermally caused shifts are mainly the focus
of simulation studies due to high performance and the usage of dry processing. The accuracy with which thermal properties
can be mapped today is measurably lower than current static and dynamic properties. The reason is due to strong interaction
of the specific physical effects and the complexity of pertinent constraints. With constrained parameters the impact caused
is defining the convective heat transmission. The heat transmission coefficient can be calculated analytically or numerically.
This article is presenting a method that allows permanent adaptation of this coefficient to make it possible to better apply
convective heat transmission to time-variable thermal simulations especially for mechanical based finite element models. |
