| Abstract: |
| The complexity and rigor of working environment demands the combination instrument framework must have the ability to withstand vibrations and shocks from mechanical environment, which can ensure the reliability of the devices installed. The finite element (FE) model of combination instrument framework for structural dynamics was built by commercial software MSC.Patran, relative modal analysis was realized by software MSC.Nastran. Simulation results and experiment results agreed well. That showed the modeling method and simulation technique were feasible. |
| Key words: combination instrument framework vibration modal simulation |
