Modelling of static properties of load-carrying system of machines tools using hybrid finite element method

A good design of the load-carrying system is an important task in the construction of machine tools. Load-carrying system of a machine tool is a conceptually isolated set of machine tool components that are connected by guideways. Such isolation results from the participation of these components in carrying the loads resulting from machine working processes [1]. Design of these systems requires a special attention to provide them with abilities to counteract undesired phenomena that limit machines performance. A large stiffness of these system is an essential criterion that must be met. An ever increasing machine tools end-user demands regarding the stiffness criterion
