동력경운기(動力耕耘機)의 운동(運動) 시뮬레이션을 위한 모델 개발(開發)

Development of Simulation Model for Power Tiller Motion

A mathematical model is developed and computer programmed for simulation of power tiller motion. The model consists of a main body and two driving wheels resulting in an 8 degrees of freedom system. Drawbar loading is also included by coupling the model with a sub-model representing the implement to be used. The computer program SIMPTL can predict motion characteristics and static stability of power tiller under a given set of ground and operation conditions.
