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.:
