Abstract

The aim of this study is to develop a multi-body dynamics simulation model for predicting the power requirements of a self-propelled garlic collector and to validate the model through comparison with field-measured load data under two soil conditions. A simulation model of a 40.2 kW garlic collector, comprising a driving part, a collection part, and a transport part, was developed using RecurDyn. Field experiments were conducted at Hapcheon (silt loam) and Uiseong (clay loam), and the measured rotational speeds were applied as simulation input conditions. Under the Hapcheon condition, relative errors between simulated and measured power requirements were 6.1% for the driving part, 11.4% for the collection part, and 6.0% for the transport part, with a total power error of approximately 1.8%. Under the Uiseong condition, the errors for the main components and the total required power were all within 5%. The prediction errors in the driving part were mainly associated with crawler-ground interaction under different soil strength conditions, whereas the errors in the collection and transport parts were attributed to simplified contact, friction, chain tension, hydraulic load characteristics, and field operating conditions in the mechanical models. These results indicate that the developed model can predict the total power requirement of the garlic collector with acceptable accuracy and can serve as an engineering tool for engine capacity evaluation and power transmission optimization.
