For the purposes of dynamic shock testing of engineering structures and for solving of metrology problems, a stand-alone shock-resistant digital registrar AIDA has been designed for measuring elastic and plastic dynamic deformations in the range of 100 to 50 000 μm/m. The designed system can operate under the effect of severe electromagnetic, mechanical and climatic conditions.

AIDA registrar withstands mechanical overloads up to 1, 000 g at 3,000 g×ms of the total overload in a wide range of temperatures (–40…+40^ОС). The proposed registrar has been put in operation and, contrary to the currently available devices of this type, has shown high resistance to mechanical, thermal and electromagnetic exposures. The device has eliminated the necessity of using stationary measurement systems and has improved reliability of results. In comparison with the existing contact systems, the proposed development has higher technical characteristics and metrological performances and shows improved reliability of registration.
