20.500.12556/RUL-134346 Razvoj 4/3 proporcionalnega potnega ventila za izdelavo s postopkom 3D tiska kovin Development of hydraulic proportional 4/3 directional control valve for metal 3D printing Tisk kovin se vedno bolj uveljavlja v industrijskih procesih kot alternativa konvencionalnim izdelovalnim postopkom. Tudi na področju hidravlike se pojavljajo izdelki, izdelani s 3D tiskom kovinskih materialov. Zadali smo si nalogo, da izdelamo ventil, ki bo numerično preverjen z vidika trdnosti in pretoka ter nato topološko optimiran. Zaradi narave izdelovalnega postopka je možno izdelati kompleksne notranje in zunanje oblike, kar privede do boljših karakteristik končnega izdelka. Ventil smo nato natisnili in na njem izvedli meritve hidravličnih parametrov ter jih primerjali z numeričnimi rezultati. Končan model ohišja ventila je dosegel pričakovanja in je boljši od konvencionalnega. Ključni kriteriji za primerjavo obeh ventilov so bili tokovne karakteristike, lastna teža ter končna cena. Metal 3D printing is gaining popularity in industrial processes as an alternative to conventional manufacturing. In the field of hydraulics, there is also a growing demand for 3D printed components such as valves, pumps and all kinds of housings. We were faced with the task of designing and manufacturing a hydraulic valve housing whose strength and flow properties were numerically tested and whose external geometry was topologically optimized. Because we were working with a 3D printer, we were able to design complex geometries that resulted in the improved properties of the final product. We printed the valve, measured the hydraulic parameters, and compared the results to the numerical ones. The finished product exceeded expectations and performed better than the conventionally manufactured product. The most important criteria for the comparison were the flow properties, the weight of the finished housing and the manufacturing costs. proporcionalni ventil 3D tisk kovin CFD analize MKE analize topološka optimizacija dp-Q karakteristika Q-s karakteristika proportional valve 3D print CFD analyses MKE analyses topology optimization dp-Q characteristic Q-s characteristic true false false [J.
