Efficient Simulation of the Heat Flux Input in Moving Contacts
Marian Partzsch, Michael Beitelschmidt · PAMM · 2015
Abstract In thermal simulations moving parts can be included by discretely adjusting their position within the steps of a transient analysis, whereby frictional heating is considered as a pre‐determined, time‐depended NEUMANN‐BC within the contact zone. Now when using a coarse time discretization, the rarely conducted update of the actual loaded friction is the reason for one proportion of the occurring lack in result quality. In this paper we present an idea to counter this systematic error source by some low‐effort editing of the applied load data. The proposed method is based on the conservation of the provided frictional energy between the continuous and discrete motion and considers the actually used time discretization. Its performance is shown for a simplified case at the end of this paper. (© 2015 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
