| 摘要: |
| 为将拖拉机作业机组室内仿真控制研究中模拟的作业阻力转化为拖拉机作业负荷，设计了一种拖拉机作业负荷仿真装置，由拖拉机动力输出轴、万向节传动轴、增速箱和电涡流测功机、模拟犁架和液压加载器几部分组成。试验结果表明，阻力模拟加载系统中牵引力和电涡流测功机产生的制动转矩变化规律与耕深阶跃信号变化规律相同。测功机产生的制动转矩实测值与设定值变化趋势一致。该装置能在计算机控制下实现拖拉机作业负荷的实时模拟和对机组进行各种加载试验研究。 |

| Abstract: |
| To convert the resistance from the simulated unit of the tractor-implement combination to tractor working load, a simulated unit of tractor working load is designed. It was composed of the power transmission output, universal joint and propeller shaft, acceleration gearbox and electric eddycurrent dynamometer, simulated plough and hydraulic loading device. The experiment results showed that change trend both traction produced by resistance of the simulated loading system and brake torque produced by the electric eddycurrent dynamometer were same as jump signal of plough depth. The measured value changes with setting value of braking torque. This device could realize real-time simulation of tractor working load and take many loading studies on implement units. |
