摘要

为了研究集中载荷条件下履带车辆稳态转向性能，提高转向模型精度，分析了履带张力对接地压力分布的影响，推导履带车辆接地压力分布计算模型。运用履带与土壤之间的剪切应力-剪切位移关系推导新的转向动力学模型，建立相应的动力学方程组并求解。分析了履带宽度和履带张力引起的接地压力变化对稳态转向运动学和动力学参数的影响，并通过实车试验测试对分析结果进行验证。结果表明，理论计算结果与试验数据有很好的一致性，验证了该模型的正确性。

Abstract

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.
