Damping coefficient of rubber in ns/m
WebIn the analytical investigation, a mathematical model is developed from which the stiffness and damping coefficients for rubber as well as the damped energy can be evaluated. … Damping 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. Examples include viscous drag (a liquid's viscosity can hinder an oscillatory system, causing it to slow down; see viscous damping) in mechanical systems, resistance in electronic oscillators, and absorption and scattering of light in optical oscillators. Da…
