ABSTRACT
This paper estimates the distribution parameters of wheat grain damage found in multiple loads. The influence of the impact on resistance to mechanical damage has been determined. The samples of 400 grains was multiple impacted with a metal plate with various speed from 14 m/s to 30 m/s up to the first visible grain damage. The moisture of grain was about 16%. The results of statistical analyses show that the distribution of the number of loads in which the external structure is wasted are different depending upon the speed of the impacts. When the speed of the impacts are greater than 20 m/s all the data falls within one numerical parameter. As a result the multiple loads can be investigated on grains below this speed. It was stated that multiple impacts at 8 m/s causes a lower immediate resistance without changing the internal structure.
