The causation of random vibration is introduced, and the usual design and test methods were summarized. Based on Gaussian distribution and Miner theory, the simulating analysis method and process for random vibration were put forward. Through the process of emulating and analyzing certain equipments, the practical ways to determine the boundary conditions of random vibration and to make the simulation and analysis by software were described, the problem to which must be paid attention during the simulation and analysis was point out. It can be a reliable reality method for this kind of the simulation analysis.
