Abstract

In many applications, installing an absorber/tuned mass damper (TMD) is an effective method of vibration control. To overcome the drawbacks of traditional TMDs and improve the overall performance, a bio-inspired structure (X-shaped structure) is used for a tunable and nonlinear TMD (X-absorber). In this study, multi-variable optimization, tunable stiffness and damping properties, nonlinear influence and vibration suppression performance of this novel X-absorber are systematically studied. Compared with traditional absorbers this X-absorber can provide beneficial nonlinear damping which can significantly improve system parametric robustness, tunable quasi-zero stiffness for a widen vibration suppression bandwidth with a widened anti-resonance, effectively suppress resonant peaks of ultra-low frequencies, and eliminate potential instabilities (e.g., bifurcation, detached resonance curves) inherently existing in Duffing oscillators. In the experimental testing, the robustness and effectiveness of the optimized X-absorber with different excitations are validated with comparison of a traditional spring-mass absorber. The X-absorber would provide a more reliable and flexible solution to many vibration suppression applications.
