本文通过对单块履带板滑动下陷试验研究,提出了疏松干砂滑动下陷的经验公式,并在此基础上建立了履带车辆的下陷理论预测式。同时还通过对履带车辆行驶阻力的理论分析,建立了包括滑动下陷影响在内的履带车辆行驶阻力的数学模型。整车在疏松干砂上试验表明,车辆下陷、行驶阻力的预测值与实测值有一致的趋势。
In this paper, by studying the sliding subsidence test of a single track shoe, an empirical formula for loose subsidence of dry sand sliding is proposed, and on this basis, a prediction formula for subsidence of tracked vehicles is established. At the same time, through the theoretical analysis of the running resistance of tracked vehicles, a mathematical model including the impact of sliding subsidence on the running resistance of tracked vehicles was established. The test of the vehicle on loose dry sand shows that the predicted values of the vehicle subsidence and running resistance are consistent with the measured values.
