They must work smoothly and quietly like an automotive c a transmission, but usually working conditions are much more severe. They must also be reliable r in different kind of working conditions and fields of applications. Because of the great variety of T gears and speeds selectable, calculations for safety factors and component lifetimes becomes usually very complex, time consuming and challenging to manage. In this project, a very complex and modern transmission was modelled to be able to calculate the whole tractor transmission with PTO driveline simultaneously. There are almost 300 different power flow variations and also the possibility to check against wheel slip and calculate the whole system with a load spectrum.
