In this study, an analytical study on the effect of the support structure deflection on the impact test result was carried out to set up the accurate impact test method. Various impact analyses of the CEDM(control element drive mechanisms) impact test were performed using LS-DYNA commercial FE program. Finally, the effect of the boundary condition of the support structure and impact loading duration were investigated.
