Abstract

This paper concerns about dynamic analysis of a test miner, which operates on cohesive soil. The test miner consists of loading frame, electronic equipments, crusher device, pick-up device and track system. The pick-up device is operated by two pairs of hydraulic cylinders. The total weight is about 6390kg. The numerical analysis model of the test miner is made by commercial software. The average pressureis about 8.6kPa. The degree of freedom is 758. A terramechanics model of cohesive soft soil is implemented to the software and applied to dynamic analysis of the test miner model by using user-define subroutine. The dynamic responses of the test miner are studied with respect to the track velocities, track tensions, and different types of terrain conditions.
