- This ratio describes the rate of damping. In the presence of the forces of resistance the energy of the oscillating system will gradually decrease, the oscillations Damping constant is inversely proportional to the number of vibrations that result in decreased amplitude of e. Damping constant - constant for a...
- viscous damper attached at C to provide a damping ratio = 0.7. The pointer BED pivoted to the mass at B and to the instrument casing at E. (a) Write the equation of motion of the system in terms of the vertical deflection, u , of the mass at B . (10%) (b) Find the undamped natural frequency of the system. (5%)
- LASD coated panels show high damping above 500Hz vs. CLD steel LASD performs optimally in higher modal densities structures (i.e. BIW) and at frequencies >500Hz Damping Performance Damping Loss factor Test samples: Size 0.8m X 0.8m Coated area: 0.6m X 0.6m Modal Testing - 2D Panels (PPG SAE paper 2011-01-1632)
