摘要

与传统的机械传动相比,液力传动的缺点是能效较低。然而,由于其设计灵活、几何排列和操作简单,它被广泛应用于各种工作机械,如建筑机械、越野车、森林伐木机械,特别是农业机械。在胡萝卜收获机械组合的开发项目中,液压传动是设计和实施胡萝卜收集滚筒系统的最佳解决方案。该项目旨在利用越南市场上现有的液压元件,实现系统结构简单有效的实用结果。鉴于液压传动回路种类繁多,本文基于数值模拟对潜在系统设计方案的功能和能效进行了分析,并提出了一种新的实用速度控制回路。该建议电路使用一个与液压马达平行布置的压力补偿流量控制阀。研究是在 Matlab/Simulink 仿真环境中进行的,其中的电路模型是使用液压元件构建的,其实际参数设置来自元件供应商。分析结果表明,建议的电路在功能性和经济效益之间取得了平衡。

Analysis of hydraulic drive circuit selection for a carrot collecting system
Compared to conventional mechanical transmissions, hydraulic transmission has the disadvantage of lower energy efficiency. However, it is widely employed in various working machines such as construction machines, off-road vehicles, forest logging machines, and especially agricultural machinery, owing to its flexibility in design, geometric arrangement, and simplicity in operation. In the development project for carrot harvesting machinery conjugate, hydraulic transmission is the optimal solution for the design and implementation of the carrot collecting roller system. This project is oriented towards achieving a practical result where the system structure is simple and effective, utilising hydraulic components available on the market in Vietnam. Given the myriad of hydraulic transmission circuits available, this paper undertakes an analysis based on numerical simulations of the functionality and energy efficiency of potential system design options and proposes a new practical speed control circuit. This suggested circuit uses a pressure-compensated flow control valve arranged parallel to the hydraulic motor. The study is carried out in the Matlab/Simulink simulation environment, where the circuit models are constructed using hydraulic components with practical parameter settings sourced from component suppliers. The analysis results indicate that the proposed circuit strikes a balance between functionality and economic efficiency.
