20.500.12556/RUL-183140 Konstruiranje naprave za preizkušanje razleta modelarskih koles pri različnih stanjih obremenitve Design of a device for burst testing of model vehicle wheels under various loading conditions Vožnje hitrih radiovodenih avtomobilov se zaradi mehanske odpovedi koles pogosto končajo z izgubo nadzora nad vozilom, kar lahko povzroči veliko materialno škodo in ogroža varnost. Poznavanje mejnih obratovalnih pogojev koles je zato ključno za zmanjšanje stroškovnega tveganja in zagotavljanje varnosti. V ta namen smo v zaključnem delu zasnovali napravo za preizkušanje razleta modelarskih koles pri različnih kombinacijah radialne in vlečne obremenitve. V procesu snovanja smo ugotovili, da je za modelarska kolesa najprimernejša izvedba simulacije podlage z zunanjim bobnom. Radialno silo smo preko prenosnega mehanizma zagotovili z uporabo uteži, vlečno pa z zaviranjem bobna na tornem principu. Visoko doslednost slednje je težje zagotoviti. Računska analiza je pokazala nastop visokih ekscentrično vzbujanih obremenitev ob razletu, kar je narekovalo optimizacijo geometrije konstruiranih delov. High-speed radio-controlled cars often experience a loss of vehicle control due to mechanical wheel failure, which can result in significant material damage and pose safety risks. Therefore, understanding the operational limits of the wheels is essential for reducing cost-related risks and ensuring safety. For this purpose, a test device was designed as part of the final project to evaluate the burst behavior of model wheels under various combinations of radial and traction loading. During the design process, it was determined that simulating the ground using an external drum configuration is the most suitable approach for model wheels. The radial load was applied via a transmission mechanism using weights, while the traction load was generated by braking the drum based on the friction principle. Maintaining a high level of consistency for the latter proved more challenging. Computational analysis revealed the occurrence of high eccentrically induced loads during wheel burst, which necessitated optimization of the geometry of the designed components. radiovodeni avtomobili obratovalni pogoji koles preizkušanje razleta radialna obremenitev vlečna obremenitev simulacija radio-controlled car wheel operating conditions burst testing radial load traction load simulation true false false [S.
