The mass-spring-damper system has the minimum complexity scenario which characterizes almost all the mechanical vibration phenomena. Also it is well known that a second-order differential equation can model its dynamics. However, if the damper has a magnetorheological fluid, then it shows viscoelastic...
The solution tells that such a spring-mass system oscillates back and forth as de- scribed by a cosine curve. The differential equation (4.42) appears in numerous other contexts. A classical example is a simple pendulum that oscillates back and forth. Physics books derive, from Newton's ...
The aim is to render the entire dynamical system dimensionless (by finding the dimensionless time derivative), rather than focusing solely on a single state. I didn't study your tuned mass damper with with quasi-zero-stiffness (QZS), so I provide a relatively simple example below:
One way to deal with such problem is by using other representation of the force exerted by the human operator, as for example a nonlinear PID [30] or as a five-parameter mass-spring-damper system [31]. Despite the above, the MPD allows to represent a general approximation of the cobot...

We consider now two coupled MSD-chains, which consist of 25 mass-spring-damper elements each. The chains are coupled via a spring with stiffness K_{co}, see Fig. 8. The mathematical model as pH system is given as follows. For both chains, we have \begin{aligned} {\dot{x}}_{i}&...
to produce the differential motion velocity pattern. The speed during the return portion of the half cycle is determined by the natural frequency of the conveyor's mass/spring system. At the end of the fast portion of the cycle, the clutch/brake re-engages, and the conveying member is again...
