      Requirements of specification are
      1, define multiaxial PSD excitation
      2, define different exposure time for each axis

      The question is, if I want to simulate the fatigue after random vibration, how to define the specification in ls-dyna?

      Hello EK,

      Have a look at the implicit guidelines:

      LSDYNA Guidelines for implicit analyses using LS-DYNA (ansys.com)

      Also, if you have access to the Ansys Learning Hub, you will find courses on implicit, NVH, etc.:
