Theory and application of structural synthesis of the new lever mechanisms with the multiple cylinder joints for different technology areas

Abstract

Structural synthesis of various mechanisms is the first stage in creating reliable and efficient designs of mechanisms and mechanical drives for operation in different areas of the mechanical engineering. On the one hand, structural synthesis of various mobile mechanical systems is the most complex and problematic stage in their design due to the unknown and large number (tens of thousands) of possible structural solutions, and on the other hand, it is the most important stage that determines functional characteristics and service life of the created mechanisms. The paper presents examples of creating the non-redundant mechanisms based on the structural mathematical model integer solutions of all possible multi-loop mechanisms with complex hinges of different multiplicity. Structural synthesis and substantiation of the combined cylindrical hinges effectiveness were performed in creation of new flat and spatial structures of the multi-link mechanical devices with a different number of degrees of freedom, made in the form of multilateral robot gripper, lifting mechanism, articulated lever manipulators and mobile mechanical system of the active seismic building protection.
