“…The sliding and sinking of crawlers vary in different soil conditions. To determine whether the tracked vehicle can traverse each geological condition, tests must be conducted in various ground conditions [18,19]. The transport simulation experiment was conducted under three different soil conditions (clayey soil, dry sand, and upland sandy loam), representing the most common soil types in Korean apiaries.…”

The Korean beekeeping industry is continuously declining owing to the aging worker population and a lack of automation. To solve the problem of manual transportation and low automation of transportation tools in Korean apiculture, a multifunctional beekeeping transport loading box was developed by modifying a tracked vehicle developed in previous studies. To ensure the safety of the modified beekeeping vehicle in an apiary, a dynamic analysis of the vehicle in virtual simulation conditions and a field test inside an actual apiary were conducted. Firstly, the TRACK_LM module in multibody dynamics software RecurDyn was used to model the vehicle. Then, the model was analyzed in two use cases (bee frame loading and beehive loading), three geological conditions (clayey soil, dry sand, and upland sandy loam), and two types of terrain (s-turn and 8° slope). Meanwhile, tests under similar conditions were conducted in an actual apiary. The simulation results indicated that the modified beekeeping vehicle operated stably in the simulated agricultural apiary ground (clayey soil and upland sandy loam). The maximum pitch angles in the clayey soil and upland sandy loam conditions were 11.77° and 12.74°, respectively. However, the vehicle cannot operate under dry sand conditions on a slope because it exceeded the calculated maximum angle (34°) during operation. The maximum pitch angle of only 8.8° in the apiary transport experiment proved that the modified beekeeping vehicle could be driven safely in actual apiaries. Moreover, a comparison of the field test results with the simulation results revealed that the field test further verifies the reference value and correctness of the simulation results.

“…Similarly, in Turkey, an analysis of 85 deaths resulting from tractor overturning and rollover from 2000 to 2007 revealed that 53 deaths (61.6%) occurred on fields, farmland, and ridges [8]. Results indicate that the causes of lateral overturning and backward rollover of tractors include an excessive tip angle (beyond the static safety limit), unstable and rough ground, loading conditions, and extremely high driving speed [14,[18][19][20].…”

Tractor accidents caused by lateral overturning and backward rollover during agricultural activities and general driving are common. In this study, various research cases were analyzed to identify the factors influencing the lateral overturning and backward rollover of tractors and to examine their static and dynamic stability. Studies on the analysis of the major causes of these incidents and evaluation of tractor safety were compiled. Test methods, including actual tests and simulations, were categorized, and the characteristics of lateral overturning and backward rollover safety of tractors in different studies were examined. Additionally, safety improvement measures were proposed by identifying and summarizing the causes of accidents involving agricultural machinery. Tractor safety was evaluated primarily by conducting actual tractor and simulation tests. These tests were classified into field tests, tests on scale models, spreadsheet programs, and 3D simulation programs. The primary causes of lateral overturning and backward rollover were unstable center of gravity, extremely high driving speed, and ground conditions. Given the considerable number of studies dedicated to evaluating tractor safety, various technologies aimed at preventing lateral overturning and backward rollover incidents are expected to be applied to tractors in the future. The production and testing of safe agricultural machinery are expected to contribute to a reduction in accident rates.
