Description
Summary:ABSTRACT The influence of the airflow field around the conditioning roll of a mower conditioner on the forage harvesting process cannot be ignored. Full factorial simulation tests of the airflow field of a single conditioning roll and double conditioning roll were carried out, respectively, by taking the roll type, roll rotational velocity, and roll clearance as factors. The results show that the average airflow velocity around the conditioning rolls has a linear positive correlation with the roll velocity and an exponential negative correlation with the distance from the centre of the conditioning rolls in the single roll case. In the case of double rolls, the airflow around the conditioning rolls increase with the velocity of the rolls and decrease with the increase of the clearance between the rolls. The results of the field verification test show that, compared with the measured values for the prototype, the average error of the average velocity of the airflow around the single roll, predicted by the regression model, is 6.35%. The average error of the predicted velocity of the back-feeding airflow of the double roll is 5.86%. The results are reliable and could provide a reference for the optimised design of the conditioning roll.
