Abstract:

In order to analyze effectively the turning safety of heavy vehicles, the dynamic model and lateral balance equations of the whole vehicle were established by using the Lagrange method. The allowance of sideslip and rollover were defined, and the sequences of rollover and sideslip were determined.Based on the above analysis, the influence of the factors such as cross road adhesion coefficient to the lateral stability were analyzed, Moreover, the influence of roll-yaw inertia on the stability was further investigated. Finally, the turning characteristics of a heavy vehicle were simulated. It was found that the sideslip is mainly affected by the cross road adhesion coefficient, the rollover is mainly affected by the ratio between mass-center height and vehicle width,  and the stability of the model is  affected by the product of inertia.

Key words: heavy vehicle, sideslip, rollover, safety anylysis
