Vibration damping characteristics of the cork-based composite material in line to frequency analysis

Abstract: The conducted research suggests possibility of replacing extruded polystyrene with a renewable cork-based material in laminated composite structures. Different fractions of the cork-based material of a composite laminate have been applied. The composites have been tested employing a hammer-focused vibration method. Conforming to obtained results, the cork-based material of smaller fraction has damping properties similar to those of the extruded polystyrene composite. Integrating cork into the structure of the … Show more

“…Generally, this is a very difficult task due to the complexity of the machine or device design. Typically, machines are complex multi-mass systems with many degrees of freedom, complicated structure with holonomic and non-holonomic constraints, contain elastic and damping elements, sometimes with non-linear characteristics (Karpenko & Nugaras, 2022), with clearances in kinematic pairs. Efforts should be made to reduce vibration.…”

“…The vibration isolation system is mainly divided into passive vibration isolation systems and active vibration isolation systems (AVIS). Passive isolation is commonly achieved between the vibration source and the isolated object by introducing a material with known stiffness and damping characteristics [1,2]. Once the passive vibration isolation is designed, the vibration isolation bandwidth is predetermined, which is not easy to adjust, and the low-frequency vibration isolation performance is restricted.…”

“…For example, Skrickij et al [8] studied the cavitation effect of single-tube shock absorbers by establishing mathematical models, and proposing a simplified method for evaluating the cavitation process of automotive single-tube shock absorbers. Karpenko et al [9] explored the adaptive performance of passive control systems based on frequency analysis. However, cavitation and amplitude-frequency characteristics are not studied in this paper.…”
