점착성 연약 지반용 주행차량의 견인성능에 대한 실험적 연구

Abstract

This paper is concerned with an experimental investigation about tractive performance of a tracked vehicle on extremely soft soil. A tracked vehicle model with principal dimensions of 0.9m × 0.8m and the weight of 144kg was constructed with a pair of driving chain links driven by two AC-servo motors. The tracks are configured with detachable grous-ers, of which the span can be varied. Deep seabed was simulated by means of bentonite-water mixture in a soil bin of 6.0 m × 3.7m. Slip of vehicle and torque of motor were measured with respect to experimental variables; grouser span, grouser chevron angle, driving speed, drawbar-pull weight, center of gravity and weight. L8 orthogonal table is adopted for DOE(Design Of Experiment). The effects of experiment variables on traction performance are evaluated.
