Optimizacija koncepta namenske naprave za montažo in preizkušanje ohišja avtomobilskega dela

Logar, Jernej (author), Klemenc, Jernej (mentor)

Magistrsko delo obravnava zasnovo naprave za velikoserijsko montažo oddušnika v ulitek. Naprava mora poleg montaže vsebovati še preizkušanje tesnosti sestava, da zagotavljamo 100 % kontrolo kakovosti izdelkov. Namen naloge je zasnovati nov koncept oddušnika, ki bo vplival na ceno izdelave naprave in z uporabo metode končnih elementov analizirati potek vtiskovanja. Optimalni koncept oddušnika se določi na podlagi teoretičnih izračunov in eksperimentalnega preizkušanja vtiskovanja za katerega se namensko izdela preizkušance, s pomočjo katerih se oceni velikost sile vtiskovanja oddušnika v ohišje iz aluminijeve zlitine. S povezovanjem eksperimentalnih rezultatov z računalniškimi analizami se oceni velikost koeficienta trenja med sestavnima deloma avtomobilskega ohišja. V zaključku naloge je podana tudi primerjava med teoretičnimi izračuni in rezultati, ki smo jih pridobili z metodo končnih elementov.

• Title: Optimization of the machine for assembling and testing automotive case part

Abstract

In this master thesis we deal with a design of a machine for assembling part in the automotive case parts. The machine must include leak testing for 100 % quality control of the assembly products. The objective of the thesis was to design a new concept of the part which will affect on the final cost of the machine. With final element method an assembling process was analysed. The optimum concept was choosen on the basis of the theoretical calculations and experimental testing of the assembly process, for which specimens were designed in order to measure the aseembly force during the formation of a press-fit joint. By combining experimental results with computer analyses it was determined the size of the friction coefficient between the assembly parts. At the end of masters thesis a comparison was made between the theoretical calculations and the results obtained from the finite element analysis.
