abstract:
The article describes attempts at the detection of some properties of wheat kernels by impact analysis. Impact of kernels was realized as uniformly accelerated motion (free fall) of kernels onto a force transducer from heights of approximately 83, 21 and 6 cm. The record of the impact parameters (time and force) was captured and stored by the Digital Storage Oscilloscope (DSO) for subsequent processing. The experimental apparatus is described in detail. The shapes of the impact records of kernels were different and depended mainly on the size of kernels and on their position on impact. The captured impact records were partly statistically processed.
