Abstract
Na postojećim ručnim kolicima za podizanje tereta, metodom povratnog inženjerstva napravljena je analiza principa rada sklopa i njegovih sastavnih dijelova. Na temelju analize izrađeni su 3D modeli dijelova i sklopa, kao i pripadajuća tehnička dokumentacija. Pomoću 3D modela otkrivena je masa pojedinih dijelova potrebna za daljnji proračun. Potom je rađen analitički proračun gdje se proračunavala sila u cilindru za inicijalni i uzdignuti položaj teretne platforme, kao i komponente sila koje djeluju na polugama. Dobivene sile korištene se za izradu dijagrama normalnih i poprečnih sila, te dijagrama momenata savijanja. U konačnici su izračunata naprezanja u polugama kako bi se provela provjera kriterija čvrstoće. Zatim se je pomoću alata „dinamička simulacija“ u Autodesk Inventoru tražila sila u cilindru za oba položaja teretne platforme kako bi se potvrdila relevantnost analitičkog proračuna. U konačnici, provedena je analiza metodom konačnih elemenata na polugama u oba položaja, te je dan osvrt na dobivene rezultate i postojeću verziju ručnih kolica za podizanje tereta.
Abstract (english)
On the existing small cargo cart, an analysis of the principle of operation of the assembly and its component parts was made, using the reverse engineering method. Based on the analysis, 3D models of parts and assembly were created, as well as the associated tehnical documentation. Using a 3D model, the mass of individual parts needed for further calculation was revealed. Then an analytical calculation was made where the force of cylinder was calculated for the initial and raised position of the cargo platform, as well as components of the forces acting on the levers. The obtained forces were used to create diagrams of normal and shear forces, as well as diagrams of bending moments. Finally, the stresses in the levers were calculated in order to verify the strength criteria. Then, using the „dynamic simulation“ tool in Autodesk Inventor, the force of cylinder was searched for both positions of the cargo platform to confirm the relevance of the analytical calculation. At the end, an analysis was carried out using the finite element method on the levers in both positions, and a review was given of the obtained results and the existing version of small cargo cart.
