This project is about the study and design of a combined vehicle, specifically a truck with a three-axle tandem trailer. The project will calculate the driving resistances of this kind of vehicles and all the forces related to them. The driving resistances calculated will be used to find the power and torque that the truck engine needs. Then those parameters will be used to find an adequate engine for the truck that enables it to circulate and move properly. In this project a gearbox is also going to be designed to calculate the power and torque that arrives at the driving wheels considering the loss of power. With this power that arrives at the driving wheels it will be possible to calculate the acceleration of all combined vehicle. Finally there is presented some theory about vehicle dynamics and the force needed to unload the trailer using different unload systems will be determined and compared.
