Abstract: Aiming at the problem of corn cob damage during the operation of a longitudinal-lying roller corn harvester, based on the method of mechanical modelling, it was determined that the factors leading to cob damage are the diameter of the picking roller, the gap between the two picking rollers, the height of the helical prongs and the rotational speed, and that the main force leading to cob damage is the effect of the camming prongs on the cob. The influence of the main operating parameters on the camber force on the cob was revealed using a one- factor analysis, and the strengths and weaknesses of the influence of the gap and roller speed and camber height on the cob force were analysed using a two-factor orthogonal analysis. This study proposes a method for evaluating losses using the minimum breaking force of corn kernels and the cracking force of corn cobs and stalks as the criteria. The correctness of the loss model was verified by the method of experimental comparison, and the error of the two methods was 0.5%, which verifies the correctness of the evaluation method.
