Abstract
The passive forces acting against the drive force are phenomenon that influences dynamical properties and precision of linear axes equipped with feed drives. Covers are one of important source of passive forces in machine tools. The paper describes virtual evaluation of cover passive forces using the cover complex model. The model is able to compute interaction between flexible cover segments and sealing wiper. The results are deformation of cover segments and wipers which is used together with measured friction coefficient for computation of cover total passive force. This resulting passive force is dependent on cover position. Comparison of computational results and measurement on the real cover is presented in the paper.
