Numerical Simulation Analysis of Dynamic Parameters of the Vibratory Sinking Piling System
In the premise of mechanics model and the kinetic equation, the numerical simulation model of pile-soil system has been established with MATLAB, and the numerical analytic solution of kinetic equation has been got by fourth-order Runge-Kutta. And the relationship curves between the pile-soil interface’s friction and time, displacement, acceleration and velocity of the pile have been mainly studied when the exciting amplitude is 100kN, 200kN respectively. With the work, the exciting amplitude will be obtained. In this way, the friction of the pile-soil can be decreased and work efficiency can be improved; besides this paper can also provide a further theoretical basis of pile pressing machine's dynamic optimization.
