ANALYSIS OF THE STABLE MOVEMENT OF A GEAR SOFTENER IN TERMS OF WORKING DEPTH

This article provides a theoretical and practical analysis of the stable motion of a toothed рыхлитель (soil loosener) with respect to tillage depth. The influence of variable physical–mechanical properties of soil, surface irregularities, and angular oscillations caused by external forces on the tillage depth is examined. To ensure stable operation of the toothed loosener, differential equations of its angular oscillations are formulated, and based on their solutions, the maximum deviations are determined. According to the research results, it is substantiated that ensuring the stability of tillage depth largely depends on the optimal selection of structural parameters, in particular, the stiffness of pressure springs.本文针对齿式松土器（toothed soil loosener）的耕作深度稳定运动开展了理论与实践分析。研究了土壤可变物理力学特性、地表不平整性以及外力诱发的角振动对耕作深度的影响。为保障齿式松土器稳定作业，本文建立了其角振动的微分方程，并基于方程求解得到了最大偏差值。研究结果证实，耕作深度稳定性的保障在很大程度上取决于结构参数的优化选取，尤其是压力弹簧的刚度。
