In this paper, the cross-section of a hollow shaft was designed to improve the static and vibration characteristics of a rotating shaft. With the development of manufacturing methods such as threedimensional printing, the possibility of creating various cross-sectional shapes that had not been thought of before is being introduced. Therefore, various cross-sections were considered for a lightweight and high-speed shaft. The cross-section had multiple rectangular holes around the center hole, and the dimensions of the cross-section were varied. Static and vibration analyses for the hollow shafts with different cross-sectional dimensions were performed, and the values of static deformation under maximum stress and vibration natural frequency were compared. First, the effects of the number of holes and their dimensions on these values were investigated for the same cross-sectional area. Then, the effect of the inner diameter on these values was investigated. One of the cross-sections was selected based on the static and vibration characteristics of the rotating shaft.
