This paper considers the control method of a vibration table for a vibration test system. Recently, the vibration test with a high frequency range is required for aircraft parts. Difficulty in vibration test with high frequency range is the resonance frequency of the vibration table or the testing product. First, a lot of researches to maximize natural frequency of the structure are reviewed. Secondary, to maximize natural frequency of the cantilever beam, the reshaping of the lengthening joint is discussed. CATIA V5 is used for the design and the numerical analysis. Finally, some shape of the cross section of the cantilever beam is evaluated by the numerical analysis. The best shape to achieve the maximization of natural frequency and lightening mass is proposed.
