Liquid sloshing makes force-bearing state of a tank truck be complicated, so liquid sloshing has important influences on dynamic responses of the tank truck’s front wheel shimmy system. Here, a two-axle tank truck was taken as an example, the liquid-solid interaction mechanism in liquid sloshing process was analyzed. Combining the dynamic modeling analysis of a steering mechanism, a 10-DOF dynamic model for the tank truck shimmy system was established considering the effect of clearance in the motion pair of the tank truck’s steering linkage mechanism. Using numerical analysis, the effects of liquid sloshing, vehicle speed and clearance on the vehicle shimmy response were investigated. The analysis showed that with increase in vehicle speed, the influence of liquid sloshing on the shimmy response firstly is inhibitory, then anabatic, and inhibitory again. Finally, some measures to reduce the tank truck’s shimmy were proposed according to the corresponding conclusions.
