ABSTRACT = {Articulated tracked vehicles have high mobility and steering performance. The 
unique structure of articulated tracked vehicles can avoid the subsidence of 
tracks caused by high traction from instantaneous braking and steering. In 
order to improve the accuracy of the steady-state steering of the articulated 
tracked vehicle, the velocity of both sides of the track and the deflection angle 
of the articulated point need to match better to achieve the purpose of steering 
accurately and reduce energy consumption and wear of components. In this 
study, a virtual prototype model of the articulated tracked vehicle is established 
based on the multi-body dynamic software RecurDyn. The trend of the driving 
torque and power of each track changes as the velocity difference of two sides
of the tracks and the traveling trajectory of the mass center of the front vehicle 
change in a specific condition are obtained by the experiment. The 
experimental results are compared and verified with the results obtained from 
the virtual prototype simulation. The change law of driving power in the steadystate steering process on the horizontal firm ground as changing the velocity 
difference of two sides of the tracks, the theoretical steering radius, and the 
ground friction is obtained by the virtual prototype model simulation analysis. 
The steering inaccuracy and track slip rate are used as indexes in evaluating 
the steady-state steering performance of the articulated tracked vehicle. The 
research provides references for the study of steady-state steering performance 
of articulated tracked vehicles.},
