Analys, modellering och återskapande av fordonsdynamiska rörelser i tåg
The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform. The motions of the motion platform depended on how the modelled motions were chosen to be generated. The motion model was validated by comparison of results from the model and measured values from a real train.Generation of motions was accomplished by implementation of the model in a motion platform. A virtual test track was constructed and used to test how the implemented model controlled the motion platform. The experience of the test track in the motion platform was evaluated by persons in a cabin mounted on the motion platform.
