Ernő Fülöp studied mechanical engineering at the Institutul Politechnic Bucureşti/Roumania, where in 1984 he received his Ph.D. in the simulation of hydraulic controls by computers. In 1990 he began work as a maintenance engineer for Rába Axle Company/Hungary, and since 1997 has been with the Rába Development Institute, working as a team manager of gear design. Fülöp’s activities involve the design of spline, spur, planetary, spiral bevel and hypoid gears; tooth development; evaluation of test results; noise measurements and noise analyses; and feedback of the results of tests and noise analyses into optimization of gear toothing.
