Destination:
- Reproduction of shock acceleration in the range from 1000 to 80 000 m/s².
- Calibration of measuring transducers under shock loading: definition of axial conversion factor, non-linearity of amplitude characteristics, relative coefficient of cross-conversion.
- Application as a standard measure of 1-st category according to GOST 8.137.-84
- Features:
- The installation’s principle of operation is based on the method of the ballistic pendulum. The control of the created pulse amplitude of the shock acceleration conducted with the standard measuring transducer of acceleration.
- Structurally the installation consists of a bed on which with the help of special brackets the hammer and the anvil with the built in measuring transducer are fixed. The amplitude of shock acceleration depends on the height of lifted hammer. For changing the shock duration on the hammer the installation of special gaskets made of, for example, aluminum, textolite or rubber, is provided.
