| Abstract: | Based on the rigid-body and parameterized models for electrodynamic shaker,the random vibration simulation with finite element model of testing part has been studied.According to the experimental frequency response function of the bare table,the physical parameters of the shaker are identified to build the electrodynamic shaker hybrid model with both rigid bodies and physical parameters,which can indicate the dynamic characteristics of the shaker.Then it employed the Craig-Bampton method to build the experi... |
