Abstract
Considering on the space development in the future, space scientist should play a key role. There are a lot of researchers taking part in the investigation for space and spreading the study and business chance recently. Space development moves to a project of a private enterprise from a national project. However, the cause why space development did not develop into is to have been able to offer space environment to a researcher with low cost at any time frequently. We will install the several equipments in the satellite. However without passing through the low vibration effect zone at the launching state, our preliminary mission can not be performed. In this paper, we imaged the size of satellite is ten centimeters cube and discuss the optimum structure design regarding to the analysis of the natural frequency. The method of optimum design uses first order method. This method is analysis of the initial design is performed, the results are evaluated against specified design criteria, and the design is modified as necessary. The process is repeated until all specified criteria are met.
