Analysis of Rollover Characteristics of a 12 kW Automatic Onion Transplanter to Reduce Stability Hazards

The rollover tendency of upland farm machinery needs to be carefully considered because crop fields are typically irregular, and accidents frequently result in injuries even death the operators. In this study, characteristics an underdeveloped 12 kW automatic onion transplanter were determined theoretically evaluated through simulation validation tests considering mounting position transplanting unit load conditions. center gravity (CG) coordinates for different mass distributions, static dynamic angles calculated theoretically. Simulation conducted assess angle under positions conditions transplanter. was by operating on surfaces at speeds. According physical properties transplanter, theoretical 34.5°, CG gradually moved back rear wheel axle after attaching part upward riding average simulated 43.9°. A turning difference 4.5° observed between right left sides, where a 3° occurred due variation. During stability test, variations 2~4° 3~6° recorded both high low driving speeds vehicle platform unit, respectively. overturning also satisfied ISO standard. This study provides helpful information ensuring safety rough sloped field
