Analytical Based Approach for Vibration Analysis in Modelica: Application to the Bridge Crane System
Résumé
The higher complexity of the mechatronical wind turbine system requires taking a great effort from the early stage of the design process. Wind turbine power trains are subjected to a very diverse spectrum of dynamic loads. In order to obtain preliminary information about the dynamic behavior of the wind turbine system and its operating environment, the drive system model is developed in this paper. This model contains flexible and rigid structural components in order to predict the dynamic characteristics of the torsional vibration. All these structural components are systematically coupled in one analysis model, through a simple modeling process in Modelica/Dymola environment. Making the right technology and architectural choices early in the development program, will substantially decrease rework and related costs.
