摘　　要：近年来,振动理论作为减阻技术应用于土壤耕作愈来愈受到人们重视,如何有效地减小工作阻力和降低能源功耗是其亟需解决的两大难题。为此,以应用比较广泛的振动深松铲为重点,阐述了振动耕作方式二维切削的减阻机理。同时,介绍了目前国内外的研究现状,研究表明合理选择振动方式和性能参数是使机具达到最佳减阻效果的关键。通过对比分析强迫和自激两种主要振动型式的优缺点,列举了几种振动关键机构的设计及应用;指出了振动参数对工作阻力影响程度的研究有待于进一步完善等问题。最后展望了振动控制方式向人工智能化方向转变的前景。As a new emerging technology applied to the field , the vibration theory of soil cultivation and mining has be-come increasingly important in recent years .However , how to reduce the drag and energy consumption remain to be two major problems .This paper elaborates the theory of how to reduce the drag of the mechanism of drag reduction of two -di-mensional by using the vibrating subsoiler which is widely used in vibration subsoil as an example , and presents the re-search status both here and abroad , in which shows that the reasonable selection of vibration mode and performance pa-rameters is the key to implement the best drag reduction effect .Also describes the design and application of key institu-tions of several vibrations through analyzing the advantages and disadvantages of two main types of forced and self -excited vibration , points out some issues such as the vibration parameters of traction force is not enough .And forecasts the future of vibration theory is applied in conjunction with the artificial intelligence technology .
