Razvoj in MKE analiza ogrodja robota za čiščenje površin v hlevih

Kuhar, Rok (author), Benedičič, Janez (mentor)

V kmetijstvu se vse več lastnikov kmetij zaveda, da morajo slediti tehnološkemu napredku, kot je avtomatizacija delovnih principov. Z uporabo avtonomnega robota za čiščenje hlevskih površin si kmetje olajšajo delo in prihranijo veliko časa, katerega lahko izkoristijo za druge obveznosti na kmetiji. Diplomska naloga obravnava razvoj in trdnostno analizo ogrodja avtonomnega robota za čiščenje hlevskih površin. Naloga ogrodja je, da poveže vse module sistema robota v celovit sistem. Izkazovati mora mehansko in korozijsko odpornost. V prvem delu smo s tremi iteracijami zasnovali 3D model ogrodja z vsemi mesti za pritrditev modulov sistema. V drugem delu diplomske naloge je izvedena trdnostna analiza, s katero smo obravnavali neugodne obremenitvene kombinacije. Rezultati analize so pokazali, da so napetosti v ogrodju v dopustnih mejah.

• Title: Development and FEM analysis of the robot frame for cleaning surfaces in the stables

Abstract

In agriculture, more and more farm owners are aware of the need to keep up with technological advances, such as the automation of work principles. By using an autonomous robot to clean the stable surfaces, farmers make their work easier and save a lot of time, which can be used for other farm duties. The diploma thesis deals with the development and structural analysis of an autonomous robot frame for cleaning stable surfaces. The role of the frame is to connect all the modules of the robot into a complete system. The frame must be mechanically and corrosion resistant. In the first part with three iterations, we designed a 3D model of the frame with all places for attaching the modules of the robot. In the second part of the diploma thesis, we did a structural analysis of the frame in the Abaqus software suite. We analyzed unfavorable load combinations. The results of the analysis showed that the stresses on the frame are within the permissible limits.
