INVESTIGATION OF VERTICAL DYNAMICS OF A HYDROGEN FUEL BUS

Abstract eng:
The paper deals with two approaches to the creation of hydrogen fuel bus multibody models intended for the investigation of the bus dynamic response. The basic dynamic model for vertical dynamics was derived in the form of an ordinary differential equation system and was implemented in the MATLAB system. In order to study more complex behaviour the bus multibody model was also created using the alaska simulation tool based on a relative coordinate multibody formalism. Both models were used for the studying of the bus vertical dynamics. A very important issue of missing or inaccurate model data caused by the lack of a design documentation is discussed in the paper.
