Abstract
A combined experimental and numerical methodology was employed to investigate the dynamic response of the electron storage ring dipole magnets located in the Center for Advanced Microstructural Devices (CAMD) at Louisiana State University (L.S.U.). The magnet are highly anisotropic and can not be analysed for dynamic response without knowledge of the effective elastic properties. The theory of wave propagation in conjunction with finite element analysis was used to determine the variation of the effective modulus of elasticity magnets in question. The structure of the magnet was modeled with NASTRAN. A theoretical analysis was performede that supported the experimental variation of the modulus of elasticity with variation of residual clamping stress througout the magnet. The effect of damping on the effective modulus was also examined. The dynamic response of these magnets to their seismic input were analyzed. The path of the motion of the electron and its deviation from the expected path due to seismic input were determined.
