Abstract
Accelerated impact testing apparatus which simulates the dynamic strain in golf clubs, shafts and other specimens by rapidly transferring kinetic energy to the specimen from an instrumented tup that is free to rebound. The specimen is held in place by two holding fixtures uniquely designed to provide the appropriate boundary and support conditions for the transient strain to propagate in a manner similar to that of the actual application e.g. a golf club striking a ball. Force applied to the tup is generated by compressing a spring to a predetermined length and releasing its energy through a rapidly actuated latch. Actual force applied as a function of time is measured by a load cell located in the tup and the tup velocity just prior to impact is computed from a velocity sensor signal. Acceleration of the impact event is also recorded as well as strain levels in the shaft.
