Impact Absorption Tester.
Impact Absorption Tester -
Impact absorption capacity of a helmet is determined by recording
against time the negative acceleration imparted to a head-form over
which the helmet is mounted, when dropped upon a fixed steel anvil in a
guided free fall at a specified impact velocity.
The Impact Absorption Tester for
helmets consists of a rigid frame with a heavy base plate, a set of
interchangeable steel anvils mounted on the base, a free fall guidance
system with a dolly to keep the head-form with helmet on, an arrangement
to drop the helmet from a known height on the anvil, a set of three
accelerometers mounted in three mutually perpendicular directions which
can be fitted inside a hollow metal head-form, and a data acquisition
system with suitable software to provide the test report.
