In order to accurately and efficiently predict the environment of vibration structures with elastic joints, the BUSH equivalent elastic joints unit of MSC. Nastran software was used to deduce the natural frequencies of structures with elastic joints by using the Fixed Interface Mode Synthesis Method (FIMSM).An example structure with elastic joint is designed, and both FIMSM and traditional FEM are used to calculate the first 30 order natural frequencies of the example structure. The results show that, compared with FEM, the relative calculation error of FIMSM is within ±1.31%. Consequently, via using BUSH element to simulate the elastic joint, FIMSM possesses the ability to predict the Environment of Vibration Structure considering elastic joint precisely and efficiently.
