Abstract
The paper presents the research results on the dynamic load of tractor semi-trailer on a straight road with the maximum longitudinal friction factor?xmax=0.8 at speed V0=[60, 80]km/h, being braked with 6 different braking torques. The method of structural separation of a multi-body system is used to build a 3D dynamic model of the tractor semi-trailer and the Newton-Euler equation is used to set up the system of dynamic equations of tractor semi-trailer. Matlab-simulink software is used to examine the effects of braking torque on dynamic load of the tractor semi-trailer. The results showed that, the wheel force of axle 1 is increased by 200%, but the wheel force of axle 3 is reduced about 13.3%, and the wheel force of axle 6 is reduced about 21.6%.The dynamic load factor of axle 1 is increased by 200%, but the dynamic load factor of axle 3 is reduced about 9%, and the dynamic load factor of axle 6 is reduced about 22%.
