Stiffness of a system
WebJun 22, 2024 · The displacement response of a driven, damped mass-spring system is given by x = F o/m √(ω2−ω2 o)2 +(2βω)2 . x = F o / m ( ω 2 − ω o 2) 2 + ( 2 β ω) 2 . In this equation ωo ω o represents the undamped natural frequency of the system, (which in turn depends on the mass, m m, and stiffness, s s ), and β β represents the damping ... In this section we consider various aspects of the phenomenon of stiffness. "Phenomenon" is probably a more appropriate word than "property", since the latter rather implies that stiffness can be defined in precise mathematical terms; it turns out not to be possible to do this in a satisfactory manner, even for the restricted class of linear constant coefficient systems. We shall also see several qualitative statements that can be (and mostly have been) made in an attempt t…
