Survey of Simulations with Multibody Models of Road Means of Public Transport

Popis výsledku v původním jazyce

The paper deals with the most frequent simulations with the calculation models of road means of public transport based on multibody approaches. At first the term of multibody dynamics is introduced in brief. Then most frequent simulations with road means of public transport are specified. They are driving manoeuvres (i.e. a severe double lane-change manoeuvre according to ISO 3888-1, “moose” test, steady-state skidpad driving, steady-state turning, steering returnability, braking in a curve, sudden steering-angle change according to ISO, sudden steering-angle change according to ESV, sinusoidal steering-wheel input, random steering-wheel input and traffic lane change; results provide information on the vehicle driving properties), driving operations (i.e. braking, acceleration; results inform about the vehicle driving properties), running over an artificial obstacle (outputs of time histories of dynamic forces in the axle suspension elements are input data for the calculation of the bodywork and bogie parts strain using software based on the FEM method, time dependencies of relative deflections of air springs and rates of rebound and compression of shock absorbers inform about the suitability of the used axle suspension elements), driving along an uneven road surface (results can be used for the evaluation of fatigue life of dynamically loaded vehicle parts and are often used for the evaluation of driving comfort of a driver and passengers), a slow front impact against a concrete wall (results are input data for the evaluation of the vehicle structure deformation using the FEM programs) and the influence of lateral wind (results provide information about the vehicle driving stability). The TriHyBus (abbreviation of the Triple Hybrid Hydrogen Bus) serves as an example for introducing a severe double lane-change manoeuvre according to ISO 3888-1.
