- Abstract
- This paper concerns about dynamic analysis of an underwater test miner, which operates on cohesive soft soil. The test miner is modeled by means of a commercial software(RecurDyn). The degree of freedom is 758. A terramechanics model of cohesive soft soil is implemented to the software by suing user-written subroutine. Dynamic analysis of the underwater test miner is performed. The hydrodynamic force and moment are included in the test miner's dynamics. The hydrodynamic effects on the performance of tracked vehicle are investigated by numerical simulations.
