      Knowledge of an impact of a linked mass on a behavior of machine tools is a useful guide for their designers. This paper demonstrates a general approach which leads to a set of locally optimal parameters of mass, whose connection to the machine consequently suppresses vibrations during machining. The approach is based on simulation modeling of mechatronic systems with flexible bodies. Obtained parameters can be structurally interpreted e.g. as damper or absorber for the needs of the design already in preproduction stages.

      This paper deals with an efficient way of a simulation modeling of machine tools. Manufacturers of the machine tools are now turning to advanced simulation modeling which can accurately predict the dynamic behavior of their prototype designs without physically building any parts. A behavior analysis of a machine tool structural model in both frequency and time domain is analyzed in this paper. The presented dynamic analysis of the machine tool is based on a multi-body system with a finite element model of individual flexible parts.

      This paper deals with a simulation modelling of developed mechatronic systems, which contain a flexible behaviour of individual mechanical parts. The developed process usually contains ideal models of rigid mechanical system. The presented simulation model consists of a mechanical multi-body system with flexible parts, models of actuators, sensors and control and it is used for the development of this system with respect of the mechatronic approach. The dynamic behaviour of the whole model is analysed and the flexible properties of the mechanical system are considered. The co-simulation technique is used for this task in which the multi-body model of the developed system in ADAMS is controlled by a model in Matlab/SIMULINK environment. The complex model of the developed mechatronic system can be used as the virtual prototype of the real system and its behaviour can be tested and analysed.

      This paper deals with a simulation modelling of mechatronic systems with flexible parts. The presented approach can be used for a development of the mechatronic system which contains flexible parts. Deformations of these flexible parts affect behaviour of the whole mechatronic system. The flexible parts are included in the most of engineering applications and during a development cycle the behaviour of such parts is usually assumed as the behaviour of rigid parts and spring elements. The presented simulation modelling of the mechatronic system includes the behaviour of a multi-body system with the flexible parts using co-simulation techniques and it can be useful for a control design and a better prediction of the mechatronic system behaviour especially in systems where a deformation of flexible parts is significant for a correct operation of the system.

      This paper deals with an efficient technique for the development of mechatronic systems. Individual parts of such system as mechanics, actuators, sensors, control system, etc. are designed in several passes through V-model with respects to mutual feedbacks. Based on this methodology the developed system is made as a virtual prototype and can be tested and simulated using co-simulation technique. The ADAMS and SIMULINK co-simulation is used and it is based on direct embedding of dynamic model of the mechanical system with sensors and actuators implemented in ADAMS into MATLAB environment to a control system design and a virtual prototype model tuning. So the complex model of mechatronic system applies the same implementation for design, simulation and testing.
