Analysing the state of design and experimental researches of transport vehicles' frame constructions

The state of computational and experimental studies of supporting systems of vehicles, including frames, in conditions of market relations, reducing development time and production organization was analyzed. Ways of improving the design of bearing systems, namely application of new materials and multi-objective optimization of the carriage and its components design are proposed. Authors propose a spatial mathematical model describing the complex vibrations, in which fluctuations of the motor-transmission installation and suspension are taken into account at the same time. Problems of the further development of computational and experimental methods of bearing systems in mechanical engineering are stated.
