Vorobyov Y. The scientific basis for the creation of a complex of impulse technologies and equipment for the aggregate assembly of airframes

The object of study is aggregate assembly of aircraft structures; the purpose of the research is to develop the scientific foundations of a complex of impulse technologies and equipment for the aggregate assembly of aircraft structures in the conditions of using computer-integrated technologies; research methods – analysis and synthesis of pulsed technological processes (TP) were carried out using the results of experimental research and computer modeling methods; design of pneumatic manual impulse devices PMID was carried out taking into account the results of imitation simulation and simulation of gas dynamics devices; intellectual support for making technological decisions was carried out using the electronic structure of the assembly object improved using parametric models of connections; the choice of the PMID was carried out by building a system of “light” ontologies in the METHONTOLOGY; results – a CAD of TP and PMID was created, which provides the choice of rational parameters of TP and PMID; a number of PMID have been developed, that allows to improve the quality of folding while reducing the requirements to the qualifications of performers; rational parameters of TP of in impulse joining, mandrelling, matrixless hole punching were obtained; a decision support system (DSS) was developed at the stage of technological preparation of production (TPP); innovativeness – for the first time, the scientific foundations and the concept of creating a complex of impulse technologies and equipment for the aggregate assembly of aircraft structures were developed; for the first time a classifier for the application of impulse technologies in the assembly of aircraft structures using PMID was developed and a generalized scheme for their numerical modeling was created; for the first time, a direct task for designing PMID was solved using the results of gas-dynamic calculations of the energy parameters of devices, simulation modeling at the TPP stage using the methods of virtual ergonomics; for the first time, a parametric model of the “connection” object was developed to ensure the optimal TP option and the choice of a mechanized tool, taking into consideration the design features of the assembly object; the description of the electronic structure of the product was improved with the help of connection models; it offers the intellectual core of production DSS for TPP is advisable to be implemented in the form of ontological systems; for the first time it is proposed to implement ontological systems within the METHONTOLOGY; for the first time, a methodology for assessing and calculating the economic effect of the use of impulse technologies and tooling for the aggregate assembly of aircraft structures; the implementation degree – the research results were used at the ANTONOV enterprise, in the Flight Design company, at the KSAMC enterprise and in the educational process of the KhAI; branch of application – aggregate assembly of aircraft structures.
