Abstract
The tractor semi-trailer often causes accidents when braking. In this paper, the author uses the multi-body system (MBS) method and the Newton-Euler method to establish a system of vehicle dynamics equations. Matlab-Simulink software is used to survey the braking efficiency of vehicles on a straight road with road surface profiles according to ISO 8608–2016. When a tractor semi-trailer is run straight at 80 km/h on road surface profiles A, B, and C, the slip ratio of wheels is less than 10%; the braking acceleration of the vehicle is 6.2 m/s2, meeting the requirements of ECE-R13 standard [1]. If the tractor semi-trailer is run on road surface profiles D, E, and F, the braking force value is reduced by about 23 ÷ 44%; the slip ratio of the middle and rear axle wheels reaches 100%; the braking acceleration of the vehicle is less than 5.8 m/s2, which does not meet the requirements of ECE-R13 standard [1].
