ABSTRACT:
A harmonic oscillator and motion detection system for use in measuring dynamic elastic constants of rock material samples includes a pair of masses vertically suspended from a support position by a pair of wires. At least one mass is driven by a permanent magnet with the driving coil positioned in the air gap to the magnet. The rock sample is horizontally positioned between the pair of masses such that the rock sample acts as a spring element connecting the masses, thereby forming the simple harmonic oscillator. The motion detection system includes a pair of coil-magnets mounted to each mass for use in determining the amplitude and phase of the motion of the pair of masses.
