| Abstract: | Dynamic characteristics of a resonant fixture were designed to meet relatively higher Shock Response Spectrum(SRS) testing on an electrodynamic shaker by finite element method(FEM),and the SRS of fixture under a shock was computed.The model was modified to meet the requirements of fixture by the analyzed result repeatedly.Finally,the simulation was validated by tests.The study showed that the shaker could get higher response and achieve higher SRS test level by the means of the fixture.The research could gi... |
