- Abstract
- This paper concerns about dynamic analysis of a tracked vehicle of which each track sub-system is being composed of two tracks, which operates on extremely cohesive soft soil. The tracked vehicle consists of loading frame, electronic equipments, crusher device, pick-up device and four track systems. The pick-up device is operated by two pairs of hydraulic cylinders. The total weight of the tracked vehicle is about 6390kg. The numerical analysis model of the tracked vehicle is made by a commercial software. The average pressure is about 8.6kPa. The degree of freedom is 1,508. A terramechanics model of cohesive soft soil is implemented to the software. In order to investigate steering performance of tracked vehicle, dynamic simulations are conducted for a tracked vehicle model with respect to track pitches, steering ratio.
