手扶拖拉机手把减振装置的研究

在研究工农—5型手扶拖拉机手把振动特性基础上,研制了一种手把减振装置,并根据ISO5349—1986(E)进行了减振效果评价,结果表明:振动最剧烈方向上的振动加权加速度降低了55.8％,允许受振年限延长了126.4％,减振效果良好。该减振装置结构简单,工作性能稳定,使用安全可靠,可应用于实际生产。

Study on Absorber of Vibration Transmitted by Handles of Walking Tractor

On the basis of research to be used on the handles of GN - 5 walking tractor, a new type of vibration absorber was designed. The vibration absorbing effect of the absorber was evaluated in accordance with ISO 5349-1986(E). The measured data indicated that weighted acceleration value in the direction, having the most serious vibration was decreased by 55. 8 percent, and the tolerable time of daily exposure to vibrations transmitted by the handles was prolonged by 126. 4 percent. The vibration absorber is of simple structure and stable performance, and could be put into practical production.
