Prof. Lucian Tudose and his colleague Cristina Tudose, both in force at RKB Advanced Calculations and Optimization Department, presented the paper paper “Optimal 2ZB Approximation of Optimal Profile of Rolling Bearings Cylindrical Rollers” at the 5th International Conference on Power Transmission organized by the Balkan Association of Power Transmission (BAPT) from last October 5 to 10 in Skopje (Serbia). In this paper an innovative method to find the best approximation of the optimal profile of the rollers of a cylindrical roller bearing is presented.
