Abstract:
V prispevku se ukvarjamo z optimiranjem večzgibnega pogona paha stiskalnice za globoki vlek pločevine. Sedanja konstrukcija ne izpolnjuje vseh postavljenih zahtev, zato jo želimo čimbolj prilagoditi idealnim zahtevam tehnološkega postopka. Osnovni namen je prilagoditi sedanjo hitrostno karakteristiko paha zahtevam delovanja v določenem območju. Zato je bilo treba izdelati analizo pogona in njegov matematični model ter izvesti optimizacijo. Uporabljena metoda za nelinearno optimizacijo je sekvenčno kvadratno programiranje. Ker je postopek časovno odvisen, optimizacijskega modela ni moč uporabiti neposredno, ampak je treba primer prevesti v časovno neodvisno obliko, ki je primerna za reševanje s standardnim optimizacijskim postopkom. Cilj optimiranja je določiti takšne izmere pogonskega mehanizma, ki bi čimbolj izpolnile zahteve. V sklepu je prikazana primerjava doseženih rezultatov optimirane konstrukcije večzgibalnega pogona z začetnim stanjem pred optimizacijo.

Title:
Optimization of link-drive mechanism for deep drawing mechanical press
Abstract:
This paper deals with an example of a link-drive for a deep-drawing mechanical press. The existing design has proved unsatisfactory and does not meet all the demands and constraints which are required for this metal-forming process. Optimization of the drive is therefore necessary. Firstly, the drive is analysed and a mathematical model is made. The whole process is time-dependent, so it cannot be used directly in the optimization algorithm. This mathematical model has first to be transformed into a form suitable for the standard non-linear optimization procedure and then the optimization is carried out. We use the method of sequential quadratic programming. The final objective of the optimization process is to find the dimensions of the link-drive members such that the gives requirements are satisfied in the best possible manner. In conclusion, the results are described and compared with the initial design.
