Negative Damping at Laurice James blog

Negative Damping. This expression can be positive, negative, or equal to zero which will result in overdamping, underdamping, and critical damping, respectively. Negative damping introduces the risk of system oscillation. The term γ, when positive, takes energy out of the system. A negative value of γ would be a term. The damping may be quite small, but eventually the mass comes. \(\mathrm{γ^2>4ω_0^2}\) is the over damped case. Negative resistance or negative damping. Most things when set vibrating gradually loose their energy and thus loose their amplitude of vibration. Many systems are underdamped, and oscillate while the amplitude decreases exponentially, such as the mass oscillating on a spring. In this case, the system returns to equilibrium by exponentially decaying towards zero. The negative damping characteristics of various devices are distributed. A negative damping rate is not damping but driving. Physically, it results from an external system which constantly pumps energy into your oscillator (i. What happens if γ or k are negative?
