This paper provides a brief introduction to the theoretical foundations of random vibration simulation analysis, using the random vibration simulation of a specific electronic cabinet as a case study. The processes of model building, meshing, boundary condition setting, modal analysis, and random vibration simulation analysis are described. The simulation results verify the rationality of the structural design and identify targets for optimization, providing a solid theoretical basis for subsequent product optimization and engineering practice.
