Simulation Technology Development for Dynamic Analysis of Mechanical System in Deep-Seabed Integrated Mining System Using Multibody Dynamics
Autor: Jun-Hyun Lim, Hyung-Woo Kim, Sup Hong, Jae-Won Oh, Dae-Sung Bae
Publikováno v: Minerals, Vol 12, Iss 5, p 498 (2022)
The deep-seabed mining system for mining resources consists of a mining vessel, lifting riser, lifting pump, buffer system, flexible riser, and mining robot. Because this system is exposed to extreme environments such as fluid resistance, high water

An improved direct linear equation solver using multi-GPU in multi-body dynamics
Autor: Ji-Hyun Jung, Dae-Sung Bae
Publikováno v: Advances in Engineering Software. 115:87-102
A new implementation method of the direct linear equation solver is proposed for multi-GPU.Instead of the conventional DFS-based reordering, the BFS-based reordering method is used to have more solvability regardless of the GPU memory size.Optimizati
