| Abstract: | Based on vibrational study of the characteristics of structure,the virtual prototyping model of base is established by a 3-D modeling software,Pro/Engineer.With the models,mode analysis is carried out by a finite element analysis software,msc.visualNastran.The natural frequencies and vibration shape are obtained.The simulation is proved by experiment.Based on the simulation,the mechanics capability is proved,and the main destroy form and location are indexed.The effect of the vibration is also discussed.The result shows that the structure meets the design requirement.and can be used in the vibrational fest and the stracture optimization of the base. |
