The discrete element method (DEM) is employed to model a mining pipeline as discrete rigid elements linked by flexible connectors. An innovative user-defined subroutine for parametrically and rapidly automatically building a DEM model for such long pipeline is developed in the C language in RecurDyn. A new 3D multi-body dynamic model of a total deep ocean mining vehicle-pipeline-ship system is established with the integration of developed models for subsystems. The integrated motion simulations are achieved and demonstrate that the synchronized stable motion of the total system can be well maintained during operation processesDo danes še ni bil narejen opis kompleksne dinamike celotnih sistemov za rudarjenje na globokih morjih. Izvajanje preizkusov na oceanu bi bila draga in izjemno težavna naloga, zato s tem pristopom ni mogoče vrednotiti konstrukcijskih rešitev in njihove sposobnosti za trajno obratovanje. Učinkovit vpogled v te lastnosti pa je mogoče pridobiti s simulacijami dinamike sistema. Članek opisuje razvoj točnih in učinkovitih modelov dinamike podsistemov, ki so združeni v model celotnega sistema. V jeziku C je bila pripravljena inovativna uporabniška podrutina za popis posebnega teramehanskega modela sedimentov na morskem dnu, ki je bila dodana v paket za simulacije RecurDyn/Track in nato validirana z laboratorijskimi preizkusiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
