Možnosti softwaru SinuTrain 4.7 při programování CNC obráběcích strojů / SinuTrain 4.7 tools for programming of CNC machines

Král, Zdeněk January 2017 (has links)
This master's thesis is about the possibilities of NC programming of car wheel hub component in software SinuTrain 4.7. The theoretical part is focused on the integration of the SINUMERIK 840D control system with other control systems, it contains informations about basic methods of NC programming and research relate to the field of materials used for the production of component. The practical part of the thesis includes the design and processing of technical documentation of the component, production technology and NC program. The output of this thesis is practical verified the function of the NC program by simulation in software SinuTrain 4.7.

Temperatūros įtakos automobilio rato sukibimo su kelio danga parametrams modeliavimas ir tyrimas / Research and modelling of temperature influence to car wheel grip with road pavement

Plioplys, Rimas 14 June 2013 (has links)
Baigiamajame magistro darbe atlikta mokslo darbų, skirtų automobilio rato sąveikai su skirtingos būklės ir savybių kelio danga tyrimams analizė. Atlikti eksperimentiniai tyrimai, kurių metu ištirti temperatūros pokyčiai ratui sąveikaujant su kelio danga ir jų įtaka sankybio rodikliams. Surinkti, susisteminti, statistiškai apdoroti ir išanalizuoti 2011 ir 2012 metais išmatuoto valstybinės reikšmės kelių naujos asfalto dangos ir rato sukibimo koeficiento duomenys. Pateikiamos baigiamojo darbo išvados. Darbą sudaro 6 dalys: įvadas, mokslo darbų analizė, eksperimentiniai automobilio rato sukibimo su kelio danga parametrų tyrimai, valstybinės reikšmės kelių naujos asfalto dangos ir rato sukibimo koeficiento tyrimas ir vertinimas, išvados, literatūros sąrašas. Darbo apimtis – 65 p. teksto be priedų, 46 iliustr., 10 lent., 32 bibliografiniai šaltiniai. Atskirai pridedami darbo priedai. / In this master thesis is performed a research studies analysis about car wheel and road interaction .
