ABSTRACT:
In the paper a method of creating a data base for simulation of urban bus running processes has been presented. Creation of that base has been presented on example of an urban bus of NEOPLAN N4020 type. For complete verification of the elaborated method of simulation which has been carried out with use up of a criterion of drive system torque, an algorithm of parametric identification of “damping matrix” has been applied with use of genetic algorithms Then a complete process of identification of nodes of loads has been presented which enables specification of a real fatigue life of any nodes of a load bearing structure.
