【摘要】 本文通过对振动作业机具工作单体的研究确定了影响机具作业性能的参数是振幅、振频、振动角和前进速度,并确定了各个工作参数的选择范围,其中振幅为8.7～15.75mm;振动频率为6～16.7Hz;前进速度为0.55～1.26m/s;振动角为-48.5°～18.7°;定义了速度比方程,用来确定振幅、振动频率和振动角是对机具的牵引力、功率消耗的影响。更多还原

【Abstract】 A single work group was studied to find the important factors in decreasing draft and power requirements.Frequency,amplitude,oscillation angle and the forward speed of the tractor are the main factors that determine the performance oscillatory tillage.To qualify changes in performance,the range of parameters were calculated,such as amplitude within the range of 8.7mm to 15.75mm;frequency within the range of 6Hz to 16.7Hz;oscillation angle within the range of-48.5°to 18.7°,the forward speed within the range of 0.55m/s to 1.26m/s.The velocity ratio was also defined to determined the effect on the performance of oscillatory tillage.更多还原
