The scientific base defined, laws and established technological procedures created, a new generation of industrial equipment implemented and improved of the industry technology with specific materials in their properties and form. It expanded the scope of the multi-axis hinge-dimensional rod systems with closed kinematic chains in the processing and preparation of new materials and products used in their cars and machine tools, chemical, construction and energy sectors, namely: - equipment for assembly, welding and painting techniques; - technology manufacturing tubular thick long products of complex internal profile treatment by hydrostatic pressure on the moving smooth mandrel in high hydrostatic pressure environment; - technology for general-purpose coatings composite powders that are used in the form of mechanical mixtures of metal and ceramic, or in the form of powder alloys. Theoretical and experimental research on new configurations of machines with mechanisms of parallel structure, their main components and mechanisms, operating and auxiliary movements. A mathematical model, which is a common position describes the structure and behavior of solids, liquids and solids in a variety of settings that allows to predict the behavior of the media in general for a wide range of influencing factors: the physical properties of the bulk material and the gaseous medium, the working body geometry, vibration parameters, phases of the interaction between themselves and with the surfaces. The mathematical model implemented in software in the form of a multi-application package that allows you to analyze the interactions of different environments and the results of the analysis to design equipment with drives of mechanisms of parallel structure. Developed a unique post processors (the program "ToolsGlide") to analyze the kinematics of machines with parallel structure, which is a personal development. The program "ToolsGlide" allows to predict the behavior of the machine tools, to analyze the kinematic characteristics, calculate the coordinates of the carriage bearing system. A feature of the software module is the ability to design equipment in an interactive mode: ? select mechanism structure of the bar variable or fixed length (bipod or biglide, tripod or triglide etc.) No change in equipment design model; ? to select the character of the executive body movement along a spatial path; ? receive numerical data about the length of the rods, bearings and hinges position in the machine coordinate system, the Euler angles for kinematic links, the angles between the rods of the mechanism; ? receive path of any characteristic point of the kinematic mechanism units such as the dimensions of the moving mechanism of the platform, as well as traces of the boom when driving executive body along a predetermined path; ? determine the dynamic characteristics of the objects. Based on these studies, a prototype piece of equipment with hinged-rod manipulators for machining and work with bulk and fluids. The approach of constructing dynamic response on a set of predetermined complex technological processing conditions as the cutting and other methods for targeted design layouts equipment with MPS. With the help of the developed program "ToolsApp" defined vibrovelocity, vibroacceleration, natural frequencies and damping coefficients of numerical values and dynamic features with MPS equipment in operation with cyclic vibration loads. Proposed methods of rational choice of the load circuit and the location of the MPS guide to the layout of the process equipment, thereby ensuring the improvement of the elastic characteristics of the end-effector of the equipment.
