Movement Characteristics Analysis and Experimental Study of the Oscillating Subsoiler
摘要
Abstract
In order to study the traction resistance , the energy consumption and the improvement of operation performance,some parameters were analyzed that affect the operation of deep loosening including vibration amplitude , vi-bration frequency , vibration angle and speed of the machine in this paper at first .Then , the movement track of three kinds of different vibration angle was studied from the motion characteristic , and the conclusion was obtained .When the vibration angle was equal to zero , the trajectory was a locking waveform , the total power consumption increased , and the effect of deep loosening was not obviously increased .when the vibration angle was greater than zero , the motion trajectory was a tilt sinusoidal waveform along the moving direction .It could be divided into forward and upward movement of cut-ting and retreat movement .The power consumption in front stage and the non oscillating subsoiler were about the same , but power consumption in retreat stage was increased greatly , the energy saving effect was not obvious .When the vibra-tion angle was less than zero , the motion trajectory was a tilt sinusoidal waveform along the opposite direction of motion . It could be divided into forward and downward movement of cutting and ascension movement .During the process of ascen-sion movement stage , the subsoiler worked in the soil which had been deeply loosened , and then the power consumption was greatly reduced.Under the condition of the forward speed of 0.2~1.78m/s, the vibration amplitude of 10mm, the vibration angle of 10.800 ~-32.400 and the vibration frequency of 0~50Hz, the single factor experiments of the oscilla-ting subsoiler were researched , and the relationship between the factors and the power consumption were analyzed .关键词
