| Abstract: | Some key components of a shaker, such as armature, extended head, skateboards, strengthening board and connection blocks, are modeled. Then the vibration responses of a combined satellite and shaker model are simulated by finite element method, and the results are compared with the test data and the traditional simulation results of satellite. The analysis of frequency and response levels shows the significance of the virtual vibration test. |
| Keywords: | virtual testing simulation finite element model shaker |
