Pneumobile Technics 5 käigukasti optimeerimine

Abstract

Pneumobile Technics 5 on suruõhusõiduk, mis on ehitatud Emersoni poolt korraldatud „International Aventics Pneumobile Competition“ jaoks. Rakenduskõrgharidus lõputöö eesmärgiks on optimeerida pneumobile Technics 5 käigukasti. Käesoleva töö käigus vähendati käigukasti massi ja tõsteti üldist kasutegurit. Eesmärgi saavutamiseks otsiti vähendatud laiusega hammasratastele sobiv materjal. Sammuti muudeti käikude arvu ja ülekandesuhteid. Kasuteguri suurendamiseks vahetati liugelaagrid kuullaagrite vastu. Arvutuste põhjal projekteeriti optimeeritud käigukast. Optimeerimise tulemusena saavutati 10% massi vähenemine ja 5% kasuteguri suurenemine.

Pneumobile Technics 5 is a compressed aircraft built for the International Aventics Pneumobile Competition organized by Emerson. The aim of the profesional higher education thesis is to optimize the pneumobile Technics 5 gearbox. In the course of this work, the weight of the gearbox was reduced and the overall efficiency was increased. To achieve this goal, a suitable material for reducedwidth gears was sought. The number of gears and gear ratios were also changed. To increase efficiency, plain bearings were replaced with ball bearings. Based on the calculations, an optimized gearbox was designed. The optimization resulted in a 10% weight reduction and a 5% increase in efficiency.
