Instability of vehicle can be defined as an unexpected response maneuver that induces disturbance, occurring in the ground plane. This can include the longitudinal, lateral, pitch, yaw, roll direction, or their combinations. Many tractor semitrailer vehicle accidents can be caused by lateral instabilities which may be classified into two types: rollover and yaw instability. Rollover occurs when centrifugal forces imposed on the vehicle during a maneuver exceed the rollover threshold of the vehicle. Yaw instability often occurs in tractor semitrailer vehicles during turning maneuver on the road with low friction coefficient. The yaw instability is shown by the loss of motion trajectory or Jack-knife. This paper establishes a dynamic model of tractor semitrailer vehicle, based on Multi-Body System Method analysis and Newton-Euler equations with Burckhardt’s tire model. This model is applied to evaluate the effect of road conditions on lateral instability of the tractor semitrailer vehicle during turning maneuver. The results can serve as the basis for determining the early warning and controlling the lateral instability of tractor semitrailer vehicle with the dynamic model.

“…Law and Janajreh developed a simplified computational tool that can be used to understand and predict the effects of various tire characteristics and truck design parameters on rollover under steady cornering and non-tripped conditions [5]. An analysis approach was proposed to assess tractor/trailer performance due to wind speed and wind gusts on slippery surfaces [6].…”

Recently, articulated heavy vehicles (AHVs) with central axle trailers have been widely used in China, especially since issuing the national standard, GB1589-2016. However, traffic accidents involved AHVs with central axle trailers occur frequently. In order to address the problem and improve the stability of AHVs with central axle trailers, this paper generates a 3 degrees of freedom (DOF) yaw-plane AHV model, and analyses its dynamic responses under a simulated evasive maneuver. The influences of different trailer parameters on the AHV high-speed stability are examined. It shows that the dominant parameters affected the stability are trailer axle positions related to its center of gravity (CG), and other trailer geometric parameters. Trailer axle position poses the most important influence on the stability.
