Recently, solving vibration problems in the prediction step is strongly required to shorten the development time. The purpose of this research is to clarify and improve vibration characteristics of products such as sporting goods by experiment and calculation. A familiar tennis racket was chosen and its vibration characteristics were investigated by actual impact test and experimental modal analysis. It was clarified that the largest vibration was generated at the first mode. Structural optimization of the simplified plate could diminish the peak by shifting the node of the mode to the excitation response point. Design variables were the masses given to the circumference or the thickness of elements.
