4. Conclusion Based on an assessment of the benefits of extending the pre-production phase of the gearbox design through experimental work and optimization using software tools such as Romax, we can say that the new prototype gearbox met noise limits even with a necessary reserve. After a detailed analysis of the results of simulation tools and measurements on the prototype, we obtained very similar results. Any deviations between actual measured data and calculation data may be due to the difference between the actual mounting of the gearbox on the real tram as it was simulated and mounting on the test stand.
