Abstract

A virtual prototype can save cost and time during the design phase of today’s machine tools. Beside the calculation of the static behavior the prediction of the dynamic behavior gets more and more important, but the calculation results are often not satisfactory. Basically this is caused by a lack of knowledge about damping properties of machine tool components and their modeling. Within a project of the German Research Foundation (DFG) the damping of roller linear guides is investigated. The measuring method used to identify the components’ damping utilizes a simulation model to separate the damping of the machine component from the damping of the test bench itself and is state of the art. This article illustrates an extended version of this measuring method which isolates the components’ damping more precisely. Furthermore a first set of results for three types of roller linear guides with different preload classes is presented.
