Abstract:
Modeling mechatronic multibody systems in the preconception phase is an extremely important step in their design process. This paper presents a pre designing method applied to a mechatronic system with regarding the vibrational aspects without going through costly design techniques. Currently, modeling of flexible structures by systems approaches is a relevant issue. In this regard, flexible elements relatively simple based on analytical method have been developed in Modelica/Dymola, creating compact analytical models. Due to the objected oriented structure of Modelica, these elements can be subsequently connected to other components (components from Modelica Standard Library) in order to study the vibrational behavior of such a system, in an early design phase. Our approach is illustrated for the drive train system of a wind turbine. Several parameters having significant influence on the vibration propagation have been analyzed. This new method will allows us performing a representative and robust modeling and simulation.
