Boboshko O. The improvement of manoeuvrability of wheeled tractors and self-propelled chassis

The subject of research: the turn process of double-axle wheeled machine. The objective of research: the improvement of maneuverability of wheeled tractors and self-propelled chassis at the expense of the combined method of turn control. Methods of the research and equipment: application of linear differential equations to describe the turn process of the wheeled machine and the synthesis of rational laws of control. Experimental methods of research: methods of electrical measurement of mechanical quantity. Theoretical and practical results: the analysis of factors which in some way influence the steerability index and maneuverability of wheeled vehicles has been conducted; ways to improve the maneuverability of wheeled tractors and self-propelled chassis while using the combined method of turn control have been determined; laws of rational turning control of the wheeled vehicle have been given. Scientific novelty is in showing up new correlations between construction parameters of control systems, methods of turn control and maneuverability indexes of wheeled vehicle, the determination of their potential. Extent of introduction: methods to choose optimal parameters of steering trapezium are used at Kharkiv Tractor Self-Propelled Chassis Plant. Estimation dependences to determine maneuverability indexes, steerability are used at Kharkiv Tractor Self-Propelled Chassis Plant and at "Ukrtractor" association in improving steering control of wheeled tractors and self-propelled chassis.
