Lizunkov A. Modes loading of hydrodrive two-modular small-sized mashine

Object of research: a hydraulic control system of working equipment of small-sized two-modular machine in the process of overlapping of two independent transitive processes.Purpose of research: improving of the working ability of the hydraulic control system of working equipment of small-sized two-modular machine on the base of loading estimations in case of overlapping of the process of braking of working equipment, that is going down and sharp starting of the machine from the rest. Method of research: are based on the principles of analytical mechanics, the theory of machines and mechanisms, the theory of reliability and also numerical and iterative methods of solving differential equations. Equipment: tensometrical converter, magnet-electrical measuring equipment, computer equipment. Theoretical and practical outcomes: There has been developed a scientifically based engineering method of calculating maximum dynamic loadings in the hydraulic control system of working equipment of small-sized two-modular machines in case of overlapping two independent transitive processes of moving the machine and its working equipment, that is issued as a computed program. There has been developed an engineering method of making a park of small-sized two-modular machines taking into account the maximum level of loading of hydraulic control system with the working equipment. There has been developed the concrete constructions of devices to reduce the level of dynamic loading of the working equipment control system. New offered: there has been determined the new laws of formation of dynamical loading of the hydraulic control system of working equipment of small-sized two-modular machine, there has been determined the new interactions of overlapping of two independent transitive processes of movement of the machine and its working equipment. Level of application: has been introduced in the municipal road-repairing enterprise at KIROVOGRAD municipal communal-dwelling facility service, company "Kirovogradecology" collectiveenterprise "Kirovograd repair-mechanical plant named after V.K.Taratuta". Field of applications: machines for the land and road works.
