It aims to identify the mass and damping are most suitable for use in absorber system. Once seen, the mass of 1.0 kg more suitable for use as a percentage reduction or vibration amplitude is the highest of 40.99%. The damping values shows that the percentage reduction in the amplitude of the vibration or spring, 10 N / m is 44.64%.
