Abstract.Subject of the research is a device for determining shock force during the structures dynamic testing. Objective of the research is to create a device, which would be able to evaluate a shock force on the geocomposite structure for determining interdependence between the shock force and parameters of oscillating processes in the tested structure. The article presents design of the new developed device, which can measure a shock force on the structure surface and visualize the acquired information. A shock piezoaccelerometer is used as a primary device for measuring the shock force. The obtained signal is then fed to comparators for comparing the signal level. The processed signal is then stored in the memory chips till the shock force value is registered. A special button is assigned to clear the memory banks. Block of eight LEDs displays the shock force value.

Keywords: device, piezoaccelerometer, geocomposite structure, shock force indicator, shock force.
