damping

damp down

1. To moisten something. A noun or pronoun can be used between "damp" and "down." I have to damp down my hair before combing it, or else it just sticks straight up.

2. To make a fire or flame less intense. A noun or pronoun can be used between "damp" and "down." The room's getting too hot now, so damp down the fire.

damp off

To die after overexposure to water. Typically used in reference to plants and seeds. I'm worried that days of torrential rain will cause the flowers I just planted to damp off.

damp off

Vibration damping thermoplastic elastomers (VDT), also known as energy dissipating TPEs, can significantly reduce vibration when used in place of non-damping elastomer polymer systems.

Novel developments in vibration damping thermoplastic elastomers

The group contribution analysis method is used to calculate theoretical TA values and develop a relation between the contribution of each functional group and damping properties.

where [D.sub.i] is the damping percentage of component i, T[A.sub.i] and T[A.sub.c] are the TA value of component i and composite, and T[A.sub.c,0] is the TA value of composite at 0 wt.% content of component i.

When excited at this resonant frequency, the magnitude of the response is dependent on stiffness and damping. As damping changes, the natural frequency changes very little, but the gain's magnitude changes significantly.

Improving the Accuracy of Dynamic Vibration Fatigue Simulation

Two orders of the reference frequency can be easily and appropriately selected to determine Rayleigh damping coefficients when the degree of freedom of a structure is low or the dynamic response of this structure is controlled by some low-order modes.

Computation of Rayleigh Damping Coefficients for the Seismic Analysis of a Hydro-Powerhouse

The damping force adjuster for the semi active damper is composed of a linear solenoid and has a characteristic where the damping force increases in proportion to the control current i.

(3) Based on the well-known fact that internal and external damping can be transformed to Rayleigh damping, it is shown that the damping coefficients can be effectively determined using proportional damping and two damping coefficients can be reasonably estimated for real systems through a parametric study of damping coefficients in association with flutter loads of Beck's columns.
