Maneuverability and stability of an articulated bus for bus rapid transit system.

The mathematical model of an articulated bus with a system of turning a hook-and-loop section for a dynamic way of turning is developed. For the developed model, indicators of maneuverability and stability of the bus were appointed. The model is based on a model of a vehicle with a trailer. The input of the design parameters of the bus and the trailer, the transfer ratio of the control drive and the magnitude of the moment to the indicators of the maneuverability of the bus are analyzed. On the basis of the results, in the analysis of the rational values of the gear ratios, which ensure the proximity of the trajectories of the characteristic points of the bus and the trailer, the value of the gear ratio of 0.85 was selected, which ensures the minimum value of the steering wheels' moment.
