地震振动器基本机械模型阐明了产生压缩波的方法,但描述该系统的全响应却十分不充分。为了对实际工作在地层复阻抗中的振动器作出模拟,本文引入了简单机械系统的电模拟。用这种方法,如果由正弦力来驱动基板,那么其振幅响应和相位响应分别与简单网络中的电压及电流等效。落重法震源的作用可以用类似的模拟进行描述,然后,再与振动器及其它震源加以比较。 The basic mechanical model of an earthquake vibrator illustrates the method of generating compressional waves, but describing the full response of the system is inadequate. In order to simulate the vibrator that actually works in the complex impedance of the formation, this paper introduces the electrical simulation of a simple mechanical system. In this way, if the substrate is driven by a sinusoidal force, its amplitude response and phase response are equivalent to those of a simple network, respectively. The function of a focal-loss source can be described by a similar simulation and then compared with the vibrator and other sources.
