Abstract

U ovom radu konstruirana je prikolica za traktorsku kosilicu s ovjesom. U okviru rada je napravljen pregled postojećih rješenja na tržištu i uvid u konstrukcijska rješenja dijelova prikolice te vrsta ovjesa na konstrukcijama auto-prikolica. Na temelju njih proveden je konstrukcijski proces unutar čega su razmatrani predviđeni slučajevi u kojima će se prikolica koristiti. Nakon toga je prema zadanim parametrima mase te izračunate krutosti odabrane opruge, provedena analiza vibracija kako bi se odredio optimalan parametar prigušenja za sustav ovjesa na prikolici. Na osnovu dobivenih podataka provedena je konstrukcijska razrada, te je napravljena provjera zadovoljava li nosiva konstrukcija potrebne proračune čvrstoće i kritičnih spojeva. U konačnici izrađeni su 3D modeli te je izrađena tehnička dokumentacija u programskom paketu SolidWorks.

Abstract (english)

In this paper, a trailer with suspension for a tractor mower was designed. As part of the study, an overview of existing market solutions was conducted, along with an analysis of the structural designs of trailer components and types of suspension systems used in car trailer constructions. Based on this, the design process was carried out, considering the expected scenarios in which the trailer will be used. Subsequently, using the given mass parameters and the calculated stiffness of the selected spring, a vibration analysis was performed to determine the optimal damping parameter for the trailer suspension system. Based on the obtained data, the structural design was further developed, and a verification was conducted to ensure that the load-bearing structure meets the required strength calculations and critical joint assessments. Finally, 3D models were created, and technical documentation was prepared using the SolidWorks software package.
