The Synthesis, Designing and Analysis of the Spatial Mechanisms with Imposed Constraints
The present study provides structural synthesis, designing of 3D models and kinematic analysis of the developed spatial one-and two-movable mechanisms with imposed constraints. These mechanisms have an opportunity of technological application as mechanisms for cutting the complex internal surfaces of machine elements. The mechanisms produce a special kind of screw motion which is the most suitable means for cutting of complex spatial surfaces. Structural synthesis was based on mathematical solution of universal structural system where numbers of kinematic pairs and movable links were calculated. 3D-modelling analysis allowed to identify motion paths of their output links with machining tools. This investigation results gave an opportunity to analyze the tools motion, optimize their constructions and use of relevant parameters, and design their motions to obtain specified surfaces of machine elements.
