Numerical Simulation and Experimental Study on Mechanical Collision of Sweet Potato Harvesters
In order to optimize the harvesting height of sweet potato harvesting machines,this study conducted an in-depth investigation into the damage incurred under mechanical collision conditions for the"Su-Shu 8"variety.By employing finite element analysis and experimental methods,the mechanical behavior of sweet potatoes and their damage under different fall heights were systematically studied.Sweet potato models were accurately built using Solid-Works,considering various characteristics,to establish precise finite element models.Through finite element analy-sis,the distribution of collision stresses at different heights was determined,and initial numerical simulations identi-fied 0～250 mm as the safe mechanical collision height for sweet potatoes.Subsequently,sweet potato collision exper-iments were conducted,confirming that damages significantly increased when fall heights exceeded 250 mm,exhibi-ting distinct dark brown patches.Consistency analysis between experimental and theoretical results validated the reli-ability and effectiveness of the study.Summarizing and analyzing the experimental outcomes led to the determination of 250 mm as the optimal harvesting height for sweet potato harvesting machines,providing crucial guidance for safe transport during harvesting.
