Methodology of System Analysis of Power Distribution among Drive Wheels of an All-wheel-drive Truck

摘要

This paper is devoted to development of methodology of system analysis of power distribution systems and methods of synthesis of objective laws in the power distribution among drive wheels of a multipurpose wheel vehicle. The methodology of system analysis provides for formulation of the problem; structural analysis of power distribution systems; the synthesis of objective laws in the power distribution; development of methods for their implementation. The methodology is based on the theory of the synthesis of technical systems. In this paper parameters of characteristics of control actions have been determined in accordance with specified requirements to effectiveness of the multipurpose wheeled vehicle expressed in the form of formulated performance criteria. The main stages of the methodology for determining of the objective laws of the power distribution among the drive wheels of a vehicle are: formulation of the optimization problem; computational procedure and definition of the basic laws of the power distribution; adaptation of the basic laws, and assessment of the effectiveness of proposed solutions. We have developed a new principle of power distribution, providing the required level of mobility of the multipurpose wheeled vehicle. Application of the methodology of system analysis allows us to improve the quality of design of the systems of power distribution among drive wheels and to design multi-purpose wheeled vehicles with optimal parameters.
