摘  要:
A mechnical model of a small vibration impact pile driver is established and a hypothesis of three stage is advanced based on the analysis of its moving process. On the basis of the hypothesis, the dynamic characteristics in each stage of the driver's operation and its impacting condition are analyzed. Finally, the relationships among the main parameters during impacting process, such as oscillating frequency of exciting force, spring constant and phase differences are established to obtain an optimum condition of impacting.
