Energy dissipated by damping

WebApr 13, 2024 · When a harmonic force is applied to an oscillatory system, there will be an energy dissipation due to damping forces. The dissipated energy is calculated experimentally from the hysteresis loops, then equated to the energy dissipated by the damping sources (Air damping, PZT material damping, and Tissue damping) (Dwairi … WebMay 2, 2024 · 3. Chestermiller said: The answer is not zero when viscous damping is present. The energy lost in the damper and the energy stored in the spring equals to the kinetic energy of the mass. But you do not answer my question. I don't want to calculate the damper energy indirectly, via the kinetic energy of the mass and the spring energy.
