可控震源重锤行程计算

Calculation of vibrator reaction mass stroke

可控震源正常激发的低频信号需要震源提供足够的活塞运动行程来保证,重锤行程是制约可控震源低频特性的重要因素。深刻理解重锤行程,对于拓展可控震源低频特性具有重要的意义。本文通过介绍可控震源重锤行程的计算,希望能够为可控震源设计提供有益的参考。

Normal low-frequency excitation signal requires sufficient piston stroke provided by vibrator.Reaction mass stroke constrains the low frequency of vibrator.The lower frequency,the longer piston stroke should be designed.It is important to learn about reaction mass stroke for expanding the low frequency of vibrator.We hope to supply the useful references for the vibrator design through calculating the reaction mass stroke in the paper.
