Drop test frame
Impact test set-up based on a free-fall drop of an instrumented hammer. The drop heights range from 1 to 200 cm and can be controlled by means of an electronic hoist and release mechanism. An anti-rebound system consisting of a pneumatic brake system triggered by a contact-type switch is used to stop the hammer after the duration of impact is completed. The experimental set-up consists of free weight, frictionless bearings along the drop columns, load cell, connection plate, accelerometers, and a set of threaded rods. The hammer releases from a predetermined drop height by means of a Lansmont-manufactured electronic brake release mechanism.
