摘要
系统既可以在室内模拟加载扭矩类负荷,又可以在田间模拟再现实际牵引力负荷。模拟加载了正弦波、锯齿波、插秧机载荷谱和拖拉机田间作业时的实际负荷。x2检验结果表明,在水平0.05下,模拟曲线的分布均服从其样本信号。
The loading system developed can be used either indoor to simulate a torsional load or to duplicate an actual drawbar load in the field. Utilizing the system, sinusoidal load, saw-tooth load, load spectrum and actual load obtained when a tractor was being operated in the field were simulated. It is shown by X2 examination that the distribution of all simulated load curves accords with that of their sample curves under level 0. 05.
