Technique of functional unification of adaptive hydraulic drive module capable of load stabilization on the working body of mobile machines

Introduction. Issues on the functional unification of the adaptive hydraulic drive module are studied. For the first time, self-adapting mechanisms are considered taking into account adaptive intercommunication of the load control and agreement of motions on the working body of the mobile machines. The work objective is to create and analyze the technique of the functional unification of the adaptive hydraulic drive module. In the furtherance of this goal, a number of tasks are solved. The selection of technical equipment – unified adaptive hydraulic drive modules of the mobile machines – is validated. The methodology and indicators of the module functional unification are described. Intercommunications are considered: direct positive and back negative ones. Their effect on the functional unification property of the adaptive module is shown.Materials and Methods. For the synthesis and analysis of the functional unification indicators of the adaptive module, a similarity method of the technical systems operation is adopted.Research Results. Techniques for structural-functional unification of the self-adapting modules are developed. Optional versions of the unified modules modification and proper combinations of hydraulic motors, regulating equipment, and mathematical models of adaptive communications are presented. Criteria and indicators of similarity are proposed. The functional unification of the adaptive intercommunications of the module and different types of the hydraulic motors and fluid throttling elements in the hydraulic system are analyzed. Recommendations for implementing the functional unification under typing and operation (adjustment) of the adaptive module are formulated.Discussion and Conclusions. The methodology is recommended for the functional unification of the hydraulic self-adapting module. It can be used for the development of unit sizes and under its operation as an independent drive or a hydraulic drive subsystem of a multifunctional or combined machine.
