실험실 조건하에서 피스톤 코어 퇴적물의 음향특성 측정을 위한 초음파 측정 시스템 개발

Abstract

In this paper, we introduce PICAM(PIston Core Acoustic Measurement) system to measure the acoustic properties of the piston core sediments without its incision. The PICAM system is consist of waveguide box, verical linear motion guide, andcontrol unit.The piston core sediment is penetrated through the hole in the waveguide box. Transmitter andreceiver for acoustic measurements of the core sediment are fixed on both sides of the waveguide box,respectively. The waveguide box can be moved up and down for acoustic measurements by verical linear motion guide and control PC. The frequency band for acoustic measurements is from 70 kz to 700 kHz.The acoustic properties of the piston core sediment measured from PICAM system are compared withtheoretical predictions based on Biot-Stoll model received acoustic signals through the piston coresediment.ontrol unit.The piston core sediment is penetrated through the hole in the waveguide box.
