Vibration Analysis and Vibration Damping Device Design of Power Tiller

[摘要] Power tiller is one of the most representative agricultural machinery in hilly mountain areas of China. While the excessive vibration of the power tiller caused great physical and psychological harm to its operators. The object of this study was to present the generation and transmission mechanisms of vibration on the power tiller, and provide several measurements for the vibration isolation and damping. A dynamics model of the single cylinder engine was established firstly. Based on the analysis of the vibration transmissibility, the vibration-absorption mechanism and the critical path of the vibration control are proposed. Finally, an isolation device was designed and developed to reduce the handle's vibration of the power tiller.
