The paper considers experience in using a new type of the active impact force sensor being structurally similar to a magneto-elastic transducer to study certain dynamic characteristics of the viscoelastic multilayer barrier exposed to an impact. Two different viscoelastic materials were compared in terms of their ability to reduce the external impact peak force and energy, as well as to stretch the impact pulse over time. The work makes it possible to experimentally substantiate a possibility of constructing methodology for studying the media dynamic characteristics and the impact process parameters using the impact contact force sensors.
