초록

현대 사회의 농업 인구의 고령화 및 감소로 농업 환경 개선이 필요한 실정이고 대표적인 문제 중 하나이다. 그리고 대부분의 작업체계에서 항상 운반 작업이 필요하기 때문에 운반 작업에 사용되는 시간과 노동력의 비율이 매우 높다. 이에 따라 많은 종류의 운반차들이 개발되고 판매되고 있으며, 초기에는 대부분 화석연료를 사용하는 동력운반차가 주종을 이루고 있다. 그러나 최근에는 지구온난화와 기후변화협약 등 국제 환경규제의 강화 및 화석연료의 고갈로 인한 수소, 연료전지, 태양광, 바이오 등 차세대 친환경에너지를 주목하고 있다. 그래서 본 연구에서는 화석연료를 대체하는 친환경적이며 누구나 쉽게 조작이 가능하고 안전한 농업용 전기운반차를 개발하는 것을 최종목표로 한다. 농업용 전기운반차의 광범위한 차속 조절 및 안정성 확보에 초점을 두고 설계하였으며, 성능 및 디자인을 고려하여 프레임, 주행부, 조향부, 컨트롤러 시스템 등으로 구성되어 각 부분별 검토하였다. 본 연구의 농업용 전기운반차가 젊은 인력이 부족한 농경사회에서 고령노동자나 여성들이 쉽고 편하게 작업을 할 수 있고 높은 효율성을 통해서 농경사회에 도움이 될 수 있을 것이다.

The aging and declining agricultural population in the modern society requires improvement of the agricultural environment and is one of the representative problems. And since most of the work systems always require a transport work, the ratio of labor consumed in the transport work is very high. Accordingly, many types of transport vehicles are being developed and sold, and in the early days, most of them are powered transport vehicles using fossil fuels. However, it is paying attention to next-generation eco-friendly energy such as hydrogen, fuel cells, solar power, and bio due to the strengthening of international environmental regulations such as global warming and the Convention on Climate Change and the depletion of fossil fuels. Therefore, in this study, the ultimate goal is to develop an eco-friendly, easy-to-operate, safe agricultural electric vehicle that replaces fossil fuels. It was designed with a focus on controlling a wide range of vehicle speeds and securing stability of electric agricultural vehicles. Considering the performance and design, it is composed of a frame, a driving part, a steering part, and a controller system, and we are going to review and manufacture each part. It is believed that the manufactured electric vehicle for agriculture can be easily and conveniently operated in an agricultural society where young manpower is scarce, and can be helpful to the agricultural society through high efficiency.
