Dimensional Analysis for Bus Dynamic Performance Evaluation

Current bus regulations, as R66, and engineering bus design require testing of bus structures prototypes in order to guarantee a certain level of strength and an appropriate dynamic behavior of the bus superstructure. Experimental testing of this type of vehicles requires of big installations and space, as well as specific sensors and, therefore, can be very expensive. However, if the experimental testing is done in a scale model the infrastructure and costs would be lower than using a real bus structure prototype. Therefore, a methodology, to evaluate the bus structure dynamic performance by means of dimensional analysis and scale modeling is proposed.
