摘要
针对目前市场上的可控震源存在质量重、体积大、信号重复性差、精度低、操作繁琐、无法广泛应用于复杂地形微地震监测的问题,提出了一种轻便小型压电陶瓷震源的设计方法。从材料选型、工作原理及结构设计角度展开了初步研究。经野外测试表明:研制的轻便小型压电陶瓷震源具有体积小、重量轻、输出信号稳定、可重复、操作简便等优点,适合复杂地形的微地震监测。
Current vibrator has some problems suah as heavy mass,large volume,poor signal repeatability,low precision and complicated operation,and can not be widely applied to complex zone microseismic monitoring.Aiming at these problems,a design method of lightweight small piezoelectric ceramic seismic source is proposed.Researches are carried out from the perspectives of material selection,working principle and structure design.Field tests show that the developed compact and small piezoelectric ceramic seismic source has advantages of small,light,stable output signal,repeatable and easy to operate,and it is suitable for microseismic monitoring of complex terrain.
