This study proposes an extended model of a two-axis horizontal dynamic anti-resonance vibration isolator (DAVI). Our approach involves the incorporation of a rotatable and movable pivot pin, enabling the design of two lever mechanisms oriented along different axes to avoid disturbing the behavior of the DAVI mass. This design minimizes mutual interference and provides effective vibration isolation for both axes simultaneously. The Finite Element Method (FEM) analysis is employed to demonstrate anti-resonance and identify the corresponding band-stop filter region. Static analysis confirms the structural stability of the system under gravitational forces. Using the constructed FE model, transient analysis evaluates the vibration attenuation performance under two-axis vibration conditions, including sine signals with a 70 Hz harmonic component and measured real battleship vibration data. By applying the 2-axis DAVI, the vibration is significantly reduced, especially at 70 Hz. Furthermore, we compare the impact of restricting the pivot pin movement on vibration attenuation through additional transient analysis.
