The purpose of this study was to investigate the vibration property of tennis racket Applied with theory and experiment, the tennis racket was operated in Experimental modal analysis (EMA) and Finite element analysis (FEA). The ANSYS Software was applied in FEA. in EMA, the hammer was regarded as an actuator, accelerometers as a sensor The vibration frequency response functions of structural system & model parameters were calculated separately. The model parameters include natural frequency, damping ratio and mode shape. Through the comparison with the best natural frequency parameters between experiential value and theoretical value, it was coincident that FEM was feasibility to offer theory analysis and model to the other kinds of tennis racket as the reference on EMA, transform design, and identify quality index.
