Recently, we developed the novel damper named as Passive Damper with Anisotropic Composite Structure (P-DACS). It is consist of metal and polymer structures. P-DACS can tune static and dynamic characteristics by controlling its anisotropic of stiffness with changing several design parameters and polymer material. Additive manufacturing technology allows realizing P-DACS and also mechanical structural members such as bearings, beams embedded the P-DACS. In this paper, the influence of design parameters on the whole static and dynamic characteristics of P-DACS, and evaluating its damping performance of table which is supported by P-DACS. As the results of numerical analysis, the specific stiffness and damping ratio of P-DACS can be controlled by the design parameters. Similarly the vibration characteristics of the table supported by P-DACS is able to control with the damper design.
