Strutynsky S. Functional-oriented element base for the design of hydraulic and pneumatic drive systems

The analysis of existing elemental base for design of hydraulic and pneumatic drives was done. Architecture and structure of elemental bases was studied and their impact on the functional abilities of hydraulic and pneumatic drive systems were determined. In this study a fundamentally new element base of hydraulic and pneumatic drive systems that include complex hydraulic and pneumatic drives aggregated with micromovement system, elastically-deformed drives, hydrostatic and aerostatic hinges, including adjustable and magnetic hinges and inertial fluctuations dampers was developed . In the proposed element base we used new materials and technologies: ceramics, photo polymers, metalpolymer and ferromagnetic composites. Computer integrated Manufacturing Engineering, including laser processing were applied. The workflows in the innovative drives elements , including characteristics of flow in gaps of a hinges, ferromagnetic fluid flowing and processes in pneumatic devices were researched. The dynamic properties of the developed drive systems were investigated. The inertia characteristics of a drives were described using stochastic tensor fields of the moments of inertia with introducing tensor-gradient of a field. The planar and spatial linear and nonlinear dynamic models were used. The mathematical models for calculating the dynamic chain partial spherical motion subsystems were developed and the features of their dynamic characteristics were established. The main results of research were tested by manufacturing of drive systems, built on new element base.
