Study on Characteristics of Vibration Friction for Pile-Soil System
Vibratory pile driver-extractor is broadly applied in civil constructions, but the friction vibration theory and dynamic characteristics of friction vibration are not studied well. In this paper, the vibration friction characteristics and dynamics of pile driving process are studied based on nonlinear dynamics and friction theory. A dynamic model of system is established firstly, and then nonlinear dynamic principle and working process are studied in details. The simulation results can provide useful guidance for both vibration friction research in engineering and design in the development of such machines.
