COMPARATIVE ANALYSIS OF ANALYTICAL CALCULATION AND OPTIMIZATION ON GEARBOX DIMENSIONS AND VOLUME

Abstract

For the purposes of this research analytical and numerical calculations of gearboxes have been done. In the process of numerical calculation optimization was implemented. Optimization was done according to four different criteria: length, width, height and volume, whose values are compared to the analytical calculations according to the aforementioned criteria individually. This approach shows better gearbox performance which vary from 3% to 47% depending on the analytical calculation. The analytical calculations were conducted using suggestions from ISO standards, Petrisevic, GOST standards, and Kudrijavcev. For optimization, the Complex Box method has been used and an original software has been developed for these purposes. All real constraints have been taken into account in order to have the optimal results be usable in real applications.
