    This research presents vibration control design of a supporting structure, a Launch Vehicle Adapter (LVA) table which is specialized for small satellites and supposed to use the maximum area of mounting base of H2A rocket. Here, LVA table with three kinds of small satellites is of interest. First, the formulation of topology optimization with suggesting objectives which doesn't use modal information and keeps certain amount of robustness are mentioned. Then, relation between stiffness and topology of LVA table was examined by using the proposed formulation for vibration control uniformly throughout wide frequency domain. As a result certain robustness for vibration designing can be ensured by the topology optimization with this suggested objective function. Then the surface which was made up with data from previous topology optimization can guarantee capturing the dynamic characteristics of each satellites and shows correlation of stiffness related parameters, and can provide optimum design strategy at the initial design phase.
