摘要
通过建立高频可控震源与大地相互作用的物理模型和数学模型，得到了高频可控震源的动力学方程，分析了高频可控震源与大地震动耦合过程，给出了不同物理参数对可控震源系统幅频特性影响的曲线，为高频可控震源系统的设计提供了理论依据。
in this paper , dynamic function of portable highfrequency vibrator system(PHVS) is acquired by building mathematical and physical model of coupling process between vibrator and the earth.Curves were provided to illustrate the effect of physical parameters on the amplitude VS frequency characteristics of vibrator systerm by analyzing the coupling process. Based on above-mentioned studies thispaper provides a theoretical basis for the design of PHVS.
