Abstract

Ovaj rad obuhvaća proces konstruiranja ispitnog postolja za ispitivanje kotača gradskih bicikala prema normi ISO 4210-7:2014. Provedena je analiza normi grupe ISO 4210:2014 te je dan opis svih obuhvaćenih metoda ispitivanja kotača. Proces konstruiranja uređaja sastoji se od analize tržišta uređaja za ispitivanje dijelova bicikala prema navedenoj normi, analize zahtjeva za zadano postolje, formiranja funkcijske strukture te morfološke matrice. Temeljem morfološke matrice predložena su tri koncepta uređaja koji se prema zadanim kriterijima uspoređuju i vrednuju te se jedan od koncepata odabire za danju razradu. Odabran koncept razrađen je u CAD sustavu, izrađena je tehnička dokumentacija i odrađeni su svi relevantni proračuni.

Abstract (english)

This paper covers the process of designing a test stand for testing city bicycle wheels according to the ISO 4210-7:2014 standard. An analysis of the ISO 4210:2014 standard group was conducted, along with a description of all included testing methods. The device design process consists of a market analysis of testing devices for bicycle components according to the specified standard, an analysis of the requirements for the given test stand, the formation of a functional structure, and the creation of a morphological matrix. Based on the morphological matrix, three device concepts were proposed, which are compared and evaluated according to predefined criteria, leading to the selection of one concept for further development. The selected concept was developed in a CAD system, technical documentation was created, and all relevant calculations were performed.
