WebFinally, two bioinspired architectures are analyzed, showing significant levels of damping achieved via branching with typically 30% of the energy being dissipated in one oscillation. This concept of damping-by-branching is of simple practical use in the design of very slender and flexible structures subjected to extreme dynamical loadings. WebA new damping mechanism inspired by the architecture of trees is here identified and characterized in the simplest tree-like structure, a Y-shape branched structure. Through analytical and numerical analyses of a simple two-degree-of-freedom model, branching is shown to be the key ingredient in this protective mechanism that we call damping-by ...

Damping by branching: a bioinspiration from trees - NASA/ADS

WebDamping by branching (DBB) was identified recently by [1] as a simple mean to damp an oscillating beam, referred to as the trunk, by means of the oscillations of beams attached to it, the branches. Damping of vibration in trees originates in wood viscoelasticity and in interactions with air [2,3]. Yet, significant exchange of energy between ... WebNov 8, 2024 · Given that the amplitude is a proxy for the energy in the system, this means that more energy is added to the system by a driving force whose frequency is well-tuned to the natural frequency of the system.

WebThe difference this time however, is that a parallel resonance circuit is influenced by the currents flowing through each parallel branch within the parallel LC tank circuit. A tank circuit is a parallel combination of L and C that is used in filter networks to either select or reject AC frequencies. Consider the parallel RLC circuit below. WebMan-made slender structures are known to be sensitive to high levels of vibration, due to their flexibility, which often cause irreversible damage. In nature, trees repeatedly endure …

Webdamping induced by the blockage of antegrade perfusion. If the vessel is small in diameter and the catheter is larger than the vessel ostium, a side-hole catheter should be preferred [2]. Using a side-hole large catheter not only decreases damping, but also lowers the risk for vessel dissection that may be induced by contrast agent injection. WebDamping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation. [1] Examples include viscous drag (a liquid's viscosity can hinder an oscillatory system, causing it to slow down ...
