6.2: Spring-Mass Problems (with Damping) - Mathematics …
In this section we consider the motion of an object in a spring–mass system with damping. We start with unforced motion, so the equation of motion is my ′′ + cy ′ + ky = 0. Now suppose the object is displaced from equilibrium and given an initial velocity. Intuition suggests that if the damping force is sufficiently weak … See more

Mass-spring-damper model - Wikipedia
The mass-spring-damper model consists of discrete mass nodes distributed throughout an object and interconnected via a network of springs and dampers. This model is well-suited for modelling object with complex material properties such as nonlinearity and viscoelasticity. Packages such as MATLAB may be used to run simulations of such models. As well as engineering simulation, these sys…
