Dynamic characteristics, especially instability of an impact force measuring system subjected to impact tension loading have been studied theoretically and experimentally. The results are summarized as follows:
(1) The measuring system behaves unstable owing to the energy balance between kinetic energy of a tip and the absorption energy of the system.
(2) Instability of the system can be described by three kinds of two-degrees of freedom-mass-spring models and the transition among these models.
(3) The effects of experimental conditions such as impact velocity and dimension of a specimen on instability of the system are clarified.
