Experimental Analysis and Verification of the Influence on the Elastic Recovery Coefficient of Wheat

To establish a collision model of wheat grains impacting force plate with piezoelectric sensor, and to investigate the influence elastic recovery coefficient on sensor’s detection accuracy during process, this study employed object kinematic principles construct measurement device. This device ascertains properties collisions determines model. The variety Jinan No. 17 was selected for testing, effects contact material, grain drop height, material thickness, moisture content process were analyzed through single-factor multi-factor experiments. experimental results demonstrate that increases stiffness materials different materials. exhibits downward trend increasing falling height content, while it tends rise as thickness increases. Data analysis comparison reveal that, given determination exerts most significant effect coefficient, followed by is less pronounced. findings can provide data support simulation testing product design combine harvester cleaning screen body mechanisms seeders.
