굴삭기 트랙의 궤도 이탈현상에 관한 해석적 연구

In this paper, an analytical investigation on the track separation mechanism for tracked excavator was studied. Relative motions of track links, sprocket, idler and support rollers are very important in the driving of an excavator. The interference and friction between each components lead to noise and vibration. And also this has a great influence on the life for tracked excavator. RecurDyn program was used for the three dimensional modeling of the track assembly. Investigating the interference between sprocket and track links, the mechanism of the track separation was analyzed.
