Abstract
In this paper, a new coupling simulation method is proposed for baler picker using automatic dynamic analysis of mechanical systems (ADAMS) and discrete element method (DEM). Field tests are carried out to verify the accuracy of the simulation model. By using the coupling method, not only was it obtained that the forward velocity (FV) and the ground clearance of spring teeth (GCST) are positively correlated with the pick-up loss rate (PLR), but also that the blockage of the picker mainly occurs in the straw pushing area, and an optimization plan is proposed. Through the analysis of the acting force (AF) between the roller and the track groove, we speculate that the structure of the track groove in a certain area is defective. The coupling method and optimization scheme proposed in this paper can provide a reference for the optimal design of the picker.
Highlights
Field tests are carried out to verify the accuracy of the simulation model
Increasing the forward velocity (FV) and the ground clearance of spring teeth (GCST) leading to the rising pick-up loss rate (PLR) can be explained as follows: When the rotation speed of the picker is constant, the ability of the picker to transport straw backward remains unchanged
With the increase of the FV, some straw will be squeezed and piled up in front of the picker, which will increase the probability of straw spillover and increase the PLR
