HDD has been easily exposed to the external shock and vibration because HDD has to apply to mobile devices. Therefore, the stiffness of base has been the important factors for the design of HDD. To improve the stiffness of base, the frame was applied to the base. First, the finite element model of the base was constructed. Then, the FE model was verified by modal analysis. Drop test was performed to confirming the shock simulation model. The dynamic characteristic of original base which is verified is compared with the base which is applied the frame through modal analysis and shock analysis.

For the production method, stamp base is increasing the market share. But also, by the manufacturing method, stiffness of the stamp base is small. Many studies have been carried out in order to increase the stiffness of the stamp base. In this study, we optimally designed according to the position of bolting using a screening method in order to increase the stiffness base. After establishing a simulation model, the maximum deformation and frequency of the first mode based having relevance with stiffness of the base, were optimized. There for, it was possible to expect of increasing the stiffness of the stamp base.
