Omelnytskyi O.E. Improving the maneuverability and stability of metro buses. The dissertation on competition of a scientific degree of the candidate of technical sciences on a specialty 05.22.02 - cars and tractors. - National Transport University. - Kyiv, 2021. The critical speed of three-link metrobuses was determined, which was 32.2 m / s for a metro bus with an uncontrolled second trailer, and 29.0 m / s for a metro bus with a second controlled trailer. The lateral accelerations acting in the center of mass of separate links on which size the mode of movement was defined are defined. The mode of movement was considered stable if the acceleration of any part of the bus did not exceed 4.5 m / s2. The maximum deviations of the trajectory of the second trailer relative to the trajectory of the bus did not exceed 8.5% in circular motion; 6.1% - when turning 900; 7.2% - when performing the maneuver "permutation" and 3.5% - when moving in a straight line.
