viscous damping การใช้

• Some pickup arms incorporate viscous damping aimed at eliminating such resonance.
• Various forms of passive damping exist, including viscous damping, viscoelastic damping, friction damping, and impact damping.
• Hunter and Saxton investigated the case when viscous damping is ignored and a kinetic energy term is included in the model.
• Adaptive or semi-active systems can only change the viscous damping coefficient of the shock absorber, and do not add energy to the suspension system.
• The onset of turbulence can be predicted by a dimensionless constant called the Reynolds number, which calculates the balance between kinetic energy and viscous damping in a fluid flow.
• Energy might be lost to viscous damping, but it's unlikely it could cause any sort of total halting of the bulk motion of the inner structure of the Earth.
• It is common to add a linearised viscous damping term, B _ v to account for the strong non-linearity of the damping force, especially in the critical damping, B _ v = \ xi \ B _ \ text { crit }.
• Here, \ textstyle m represents the mass, \ textstyle u ( t ) is the displacement, \ textstyle c the linear viscous damping coefficient, \ textstyle F ( t ) the restoring force and \ textstyle f ( t ) the excitation force while the overdot denotes the derivative with respect to time.
