摘要：
In order to study the steady-state steering performances of tracked vehicle under concentrated load and improve the simulating accuracy of tracked vehicle steering model, the effect of track tension on ground pressure distribution is analyzed, and a computation model of ground pressure distribution of tracked vehicle is proposed. A new steering dynamics model is derived to establish a corresponding dynamics equation set based on shear stress and shear displacement relationships of track and ground. The effect of ground pressure change induced by track width and tension on steady-state steering kinematics and dynamics parameters is analyzed. The analysis result is verified through vehicle test. The test results show that the theoretically calculated result is well fitted with the test data, and the proposed model is proven to be effective. © 2016, Editorial Board of Acta Armamentarii.
