In this paper a technique of modelling mechatronic systems is investigated. Such technique is developed in order to build an integrated model of workpiece-fixture system additionally equipped with active deformation compensation system. The analysed type of workpieces is flexible, thin-walled parts under mechanical and non-mechanical loads. The model has been implemented in ABAQUS/Standard FEM code where the behaviour of actuator drives and a control system has been emulated with user subroutines. Model simulation data is confronted against data from experimenta investigations and theoretical calculations. Additional multi-domain simulations with the use of temperature-displacement calculation scheme, utilising the analogous deformation compensation method are described. Finally, results are discussed and conclusions are drawn.
