In this paper, the author sets up the dynamic model of the vibratory extracting-driving piling machine, and carries out the dynamic analysis, parameter calculation and Matlab's simulation for this model. Using the equation reciprocity law to carry out the calculation of soil parameter and simulation, and using the genetic algorithm to make optimization of the machine on the basis of the simulation, the author gets the optimum self-induced vibration frequencies of the machine changing with the depth of the pile and the optimization result of other parameters, thus reaching the conclusion that along with the increase of pile sinking depth, the optimum self-induced vibration frequency becomes bigger, and the vibration mass becomes smaller, hence deepening the knowledge of the dynamic performance of this system.
