The differents in impact records on varieties of barley kernel

Original language description

The article describes efforts at the detection of some differences in properties of barley kernels by impact analysis. Two varieties of barley (Czech ? PRESTIGE and Libyan ? ALRAIHAN) were compared. Impact of kernels was realized as uniformly acceleratedmotion (free fall) of kernels onto a force transducer from heights of approximately 21cm. The record of the impact parameters (time and force mainly) was captured and stored by the Digital Storage Oscilloscope (DSO) for subsequent processing. The shapesof the impact records of barley kernels were different and depended on the size of kernels, their humidity, a position of acting impact and damage of kernel. Investigating the acting of impact on germ and awn (brush) of barley kernel (two ends of kernel) was preferred, as so as a visualisation the different on impact shape between damaged and undamaged kernel. The repeated impact (with the same kernel onto the same place) brings very similar shapes of impact records as show the captured
