With annual production of 50,000 tractors, TürkTraktör is the largest producer of tractors in Turkey. The powertrains of the company’s tractors contain many gear pairs and gear groups that transmit torque through the system. For example, the transmission group includes spur and helical gear pairs. Next the torque is transmitted to the differential via a hypoid gear pair. After the differential, a planetary gear group reduces the torque. The torque is transmitted through shafts between gear pairs and most of the shafts are fastened with multiple bearings to the chassis.
With the simulation model validated, TürkTraktör engineers will begin using it as part of the design process. “We are planning to use simulation in future development projects to minimize lead time and cost,” Akce said. “We have concluded that we can accurately predict the results of a testing campaign that takes several months with only two weeks of simulation. The faster speed and lower cost of simulation will also give us the ability to evaluate more design alternatives than was possible in the past. This will make it possible to reduce the weight and cost of some parts and to increase the durability of others. Of course, the design will be subjected to durability testing as a final validation step.”
