EMERGENCY OPERATION OF A MAGLEV COACH

The article refers to brief technical description of a maglev passenger coach, which had been engineered in Russia since 1976, and of mathematical model and software for PC and workstations which permit through simulation to forecast dynamic interaction of parts and units of the coach, as well as coach’s behavior at the moment of its accident landing on the track. This model allows to determine criteria of traffic safety.

Mathematical model is represented as spatial mechanical system of 13 solids, joined by elastic dissipative elements. The system of differential equations, describing motions of the coach at the moment of its accidental landing on the track, is of 84th order. The authors used rapid not-iterated closed method of integration, designed by professor V. Husainov, where the third derivative in Taylor decomposition is represented by difference in relocation and not in acceleration. The authors describe the results of computations concerning different dynamic parameters.
