Abstract:Diplomska naloga obsega razvoj in konstrukcijo ogrodja gozdarskega vitla. Predstavljene in opisane so osnovne zahteve za razvoj ogrodja profesionalnega gozdarskega vitla. Na kratko so opisane vse obremenitve, ki delujejo na ogrodje vitla. Na novo razvito in izdelano konstrukcijo sem poleg simulacije po MKE metodi preračunal tudi na življenjsko dobo po napetostni metodi, zato da pred serijsko proizvodnjo dobimo čimbolj dovršeno konstrukcijo in izločimo kritična mesta na konstrukciji. Naloga zajema preračun in oceno življenjske dobe konstrukcije ogrodja ob uporabi visokotrdnostnega jekla Strenx. Konstrukcija ogrodja je izdelana za serijsko proizvodnjo po trenutno najnovejši tehnologiji proizvodnje kot je razrez na laserskem rezalniku, krivljenje na CNC krivilnem stroju in robotsko varjenje. Prikazani rezultati podprti s preračuni in simulacijami potrjujejo zastavljene cilje, saj smo prišli do ugotovitve, da je bilo potrebno konstrukcijo zgornje konzole še dodelati, da dosežemo ustrezno življenjsko dobo.

Title:Design of forestry winch frame
Abstract:The thesis includes the development and construction of the forestry winch frame. It presents and describes the basic requirements for the development of professional forestry winch frame. Briefly describes all of the stresses acting on the forestry winch frame. The newly developed and constructed a structure was simulated by FEM method and calculated on the lifetime expectation with stress method. With this we achieve sophisticated structure and we eliminate the critical points of the structure. The thesis includes the calculation and assessment of the lifetime expectation of the construction of the winch frame using high-strength steel Strenx. The construction of the winch frame is designed for mass production with the latest technology such as cutting on the laser cutter, bending on the CNC bending machine and robot welding. Results supported by associated calculations and simulations are confirming accomplishment goals. We found that is necessary to improve structure of upper bracket to achieve adequate lifespan. 
Keywords:FEM, dimensioning, lifespan, winch frame, stress method
