Objective: To determine key parameters for calculating dynamic effect of magnetic-levitation highspeed transport on bridge structures, carry out a dynamic analysis, and check the obtained results against experimental data and compare them with similar results on high-speed railways. Methods: In the course of the study, the method of direct integration of the dynamic problem of mo ving a mobile load along the bridge superstructure was used. Results: Computational model of a magnetic-levitation high-speed train was developed. A set of dynamic calculations was performed. Data on the magnitude of dynamic reaction of the bridge superstructure during the movement of a magnetic-levitation train were obtained. Values of the dynamic coefficient for mobile load in the speed range of up to 1000 km/h were calculated. Practical importance: Results obtained in the course of the study and the comparison made with similar data for high-speed rail transport have confirmed a significant decrease in the dynamic response of bridge superstructures when magnetic-levitation technologies are deployed. The calculation model thus developed opens up broad prospects for further research.
