摘　　要：针对我国振动沉拔桩机的仿真水平,提出一种更全面、更能反应工作效果的频域仿真法。通过解振动沉拔桩机的双自由度数学模型得到了振幅与频率的关系表达式,并根据这一结果用Matlab进行不同参数改变下的幅频响应仿真,直观地反映了随激振频率的改变,横梁和沉桩的振幅与各参数的关系。另外,对土壤参数变化下的桩机振幅也做了仿真分析,兼顾隔振的沉桩仿真为沉桩机的优化设计提供了依据。To the level of vibratory extracting - driving piling machine simulation in China , it provides a type of frequency simulation which is more overall and can reflect working effect better. Analysis of the mathematical model 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 reflects directly the relationship of each parameter and the amplitude of beam and driven pile as the changing frequency. And it also works out the amplitude simulation with the change of soil parameter. Considerations in vibrating isolation , the simulation provides evidence to the optimization design of the vibratory extracting - driving piling machine.
