Multiaxial　high-cycle　fatigue　failure　criterion　and　life　prediction　is　important　for　structural　components　under　complex　low　stress.　A　new　multiaxial　high-cycle　fatigue　damage　parameter　based　on　the　plane　of　maximum　shear　stress　is　proposed,　which　includes　the　maximum　shear　stress　amplitude,　normal　stress　amplitude　and　maximum　equivalent　normal　stress.　The　maximum　equivalent　normal　stress　is　defined　in　the　form　of　SWT　stress　function　considering　the　influence　of　mean　stress.　The　feasibility　of　the　proposed　failure　criterion　and　life　prediction　model　is　verified　by　test　data　of　different　materials.　The　predicted　results　show　that　the　life　prediction　error　of　the　proposed　fatigue　model　is　basically　within　three　times　by　comparing　with　McDiarmid,　Matake,　Crossland　and　Papadopoulos　fatigue　models.
