Abstract
Recently, environmental regulations on agricultural machinery have been increased by continuous climate change and environmental pollution. The disseminate agricultural machinery have been difficult by environmental regulations on agricultural machinery. The electrification of agricultural machinery can solve these problems. The agricultural 4WD electric vehicle platform for upland farming already have been commercialized by advanced foreign enterprises. So the need of design to develop agricultural 4WD electric vehicle platform for upland farming has been increased in domestic company. The difficult to select a motor for driving has been a problem on agricultural electric vehicle platform. Recently study, simulation have been conducted to solve the problem on agricultural electric vehicle platform. In this study, as a basic study for the development of a agricultural 4WD electric vehicle platform for upland farming, a multi-body dynamic simulation of the platform was modeled and the results were analyzed to select the motor specifications. The simulation model was constructed by using the RecurDyn program. The condition of driving speed for platform during the simulation set as 3, 5 and 10 km/h. And the simulation was conducted nomal driving conditions on the soil environment of general field agriculture(moisture content 10~20%). As a result of the simulation, the specifications of the platform were analyzed to be stably operational at 3 km/h, 5 km/h conditions of driving speed. In the future study, the study for validation and optimization of the model through a field test will be conducted.
