Abstract
A dynamic force transducer for generating vertically oriented compressional forces and motions at the surface of a solid medium. A frame is rigidly coupled in direct contact with the solid medium surface. At least one pair of identical driver units are mounted to the frame to impart vertically oriented forces to the medium. Compliant springs support the drivers and introduce mechanical resonances. The driver units are excited to produce the vertically oriented pushing and pulling forces along a common collinear vertical direction. The driver units also impart either continuous or pulsed oscillatory forces to produce prescribed seismic compressional waves in the medium.
