For　the　questions　that　the　rotating　continuously　artificial　heart　pump　would　damage　blood　cells　and　cause　hemolysis　running　at　high　rotating　speed,　this　paper　proposes　a　novel　ventricular　assist　miniscule　nutation　pump　based　on　nutation　principle.　The　novel　nutation　pump　aims　to　reduce　the　speed　of　the　rotating　parts　under　the　premise　of　necessary　flow　rate　and　without　the　increasing　of　the　pump　volume.　The　equations　for　the　pump　flow　discharge　are　obtained　based　on　the　mathematical　modeling　of　pump　flow　discharge.　The　three-dimensional　modeling　of　the　novel　ventricular　assist　miniscule　nutation　pump　is　further　established.　And　the　kinematic　equations　of　the　nutation　disk　are　deduced,　which　provides　the　basis　of　the　simulation.　The　flow　field　model　of　the　pump　is　established　and　the　meshing　grids　are　divided　in　the　software.　Finally,　the　curve　of　volumetric　flow　rate,　velocity　vector　diagram,　pressure　nephogram　and　shear　stress　nephogram　in　the　internal　pump　are　further　obtained　based　on　the　simulation　in　the　related　software.　(C)　2015　The　Authors.　Published　by　Elsevier　B.V.
