摘　　要：通过解振动成桩机的数学模型得到了振幅与频率的关系表达式，根据这一结果用Matlab软件进行不同参数改变下的幅频响应仿真，直观地反映了激振频率与各参数的关系。Analysis of the mathematical mold of vibratory extracting-driving piling machine got the mathematic relation of amplitude and frequency, and according to this result, with Matlab software we worked out the frequently simulation under the different parameters changing, and it reflected the relation with each parameter of self induced vibration frequency directly perceivedly.
