Volosnikov S. Models and methods of improving the characteristics of mobility of tracked vehicles due to implementation of automated control of the curvilinear motion

The analysis of automated control systems of tracked vehicles used in motion control systems was conducted. A method for controlling a tracked vehicle during curvilinear motion on the verge of a skid to increase the average driving speed is proposed. In order to ensure the tracked vehicle movement stability at the time of turn, a method has been developed that allows to determine the minimum turning radius at which, for a given speed and road conditions, skidding does not occur under the action of the centrifugal force. A model of the operation of a digital automated skid prevention system for a tracked vehicle has been developed, which is equipped with an automatic steering control system and does the steering by engaging gear (n-1) on the lagging board. A method for solving the problem of mathematical modeling of the movement of the center of mass of a tracked vehicle with the help of an analytical solution using the Laplace transform has been developed, allowing to carry out parametrical studies of the tracked vehicles at curvilinear motion. The criteria for estimating the main characteristics of electric motors as well as other components of the system for creating a hybrid electric drive for tracked vehicles based on serially produced components have been determined.
