| Abstract: | Aim\ To describe the FEM of spectrum analysis of random vibration response Methods Through the random vibration response analyses of beams and rectangular plates subjected to the various excitations, the FEM software PAL2/RAND2 was verified thoroughly After this, the random vibration response analysis of the basecover exposed to fluctuating air pressure was finished using PAL2/RAND2 Results The calculating results are identical with the experimental results Conclusion The FEM software PAL2/RAND2 can be used to the analysis of simple structures subjected to random excitation |
