Malashenko V. Improving of Deflashing Technology of Thermoplastics Parts based Thermal Pulse Method

An object - technology and equipment of thermoplastics parts deflashing; goal - the method development and experimental verification of the regime assignment for thermal pulse deflashing of thermoplastics parts with using advanced CAD / CAE systems. Research methods - mathematical modeling, numerical methods for solving combustion processes, heat and radiation; experimental investigations were carried out on laboratory stands of thermal pulse technologies of National Aerospace University "KHAI". Practical results - the possibility of thermal pulse cleaning of thermoplastic parts using gas-fuel mixtures has been confirmed; software and method of determining the energy characteristics and time reflow fin with thermal pulse stripping parts from thermoplastic materials have been developed; recommendations for improving the thermal pulse equipment were given. Novelty - it is proved that pre-combustion chamber flare ignition of the fuel mixture using the proposed method of prechamber geometrical parameters choice helps secure the necessary impulse for thermal cleaning degree of uniformity of the temperature of the combustion products and the suppression of the formation of shock waves; the method of determining the thermal flux in the thermal pulse treatment with pre-combustion chamber jet ignition was improved; the model to calculate the temperature distribution at the thermal pulse treatment has been improved. The degree of implementation - theresults of the thesis have introduced on Scientific and Production Corporation "FED" as recommendations of thermal-pulse deflashing regimes setting for thermoplastics part in aircraft aggregates manufacturing; the scientific and technical base for research and training is formed in the National aerospace university "KhAI". The industrial sector is aircraft building.
