【摘要】 针对传统拖拉机耕深效果差，不能很好适应各种耕作环境的问题，设计了一套新型液压控制油路，并分析其运行机理。在AMEsim软件中完成液压系统仿真模型的搭建和子模型的参数设置。对液压系统在两种不同工况下的仿真分析结果表明，在提升工况下，液压缸在3.21 s内完成提升动作；在侧倾工况下，通过PID的位置控制反馈调节，活塞杆位移误差在目标预设值的±5 mm内，满足设计要求。最后，通过试验验证了所设计的液压系统具有可行性。更多还原

【Abstract】 Considering the poor tillage effect of traditional tractors and its ineffectiveness to various farming environments, a new hydraulic control oil circuit is designed in this study, with its operating mechanism analyzed. The study completes the construction of the hydraulic system simulation model as well as the parameter setting of the sub-model in the AMEsim software. Through the simulation analysis of the hydraulic system under two different working conditions, the following results are achieved: under the lifting conditions, the hydraulic cylinder completes the lifting action within 3.21 s; under the roll conditions, the displacement error of the rod is within ±5 mm of the target preset value through the PID position control feedback adjustment, which means that the system meets the design requirements. Finally, the feasibility of the designed hydraulic system is verified through experiments.更多还原
