Radish and Chinese cabbage are the most produced and consumed vegetables in Korea. The mechanization of harvesting operations is necessary to minimize the need for manual labor. This study to develop and evaluate the performance of a multi-purpose driving platform that can apply modular Radish and Chinese cabbage harvesting devices. The multi-purpose driving platform consisted of driving, device control, engine, hydraulic, harvesting, conveying, and loading part. Radish and Chinese cabbage harvesting conducted using the multi-purpose driving platform each harvesting module. The performance of the multi-purpose driving platform was evaluated the field efficiency and loss rate. The total Radish harvesting operation time 34.3 min., including 28.8 min., of harvesting time, 1.9 min., of turning time, and 3.6 min., of replacement time of bulk bag. During Radish harvesting, the field efficiency and average loss rate of the multi-purpose driving platform were 2.0 hr/10a and 3.1 %. Chinese cabbage harvesting operation 49.3 min., including 26.6 min., of harvesting time, 4.6 min., of turning time, and 18.1 min., of replacement time of bulk bag. During Chinese cabbage harvesting, the field efficiency and average loss rate of the multi-purpose driving platform 2.1 hr/10a and 0.1 %. Performance evaluation of the multi-purpose driving platform that harvesting work was possible by installing Radish and Chinese cabbage harvest modules. Performance analysis through harvest performance evaluation in various Radish and Chinese cabbage cultivation environments is necessary.

밭 농업 기계는 심한 경사지와 험로, 재배 작물별 정형화되지 않은 재배양식으로 인해 개발이 어렵다. 특히 고추 수확 작업은 많은 시간과 인력이 요구되는 작업으로 고령화가 가속화되는 국내 농촌의 큰 문제점이다. 본 연구는 부족한 인력을 대체하고 작업 시간을 줄이며 수확 작업을 기계화하기 위해 개발된 고추 수확기의 동적 특성을 연구하고자 한다. 고추 수확기의 동적 특성을 분석하기 위해 동역학 프로그램인 Recurdyn을 이용하여 진행하였으며 모든 분석은 공차를 전제로 분석을 진행하였다. 시뮬레이션 결과에 따라 주행 플랫폼이 주행할 수 있는 안전 범위를 제시하였다.
