PROBLEM TO BE SOLVED: To provide a method for identifying a damping coefficient of a machine tool capable of identifying a damping coefficient of a support element in a vibration analysis model of the machine tool. SOLUTION: The identification method is for each of a combination creation step ...
This corresponds to the point at which the linear damping coefficient changes sign. Hence, the linearized oscillator becomes active (energy is created) when μ < 0. The Hopf bifurcation is supercritical for σ > 0 and subcritical for σ < 0. There is a saddle-node bifurcation at σ2/(4...
There are no errors messages that pop out, and the simulation run smoothly, however, when i measure the reaction force on each wheel, I get unexpected peaks that give a high force magnitude regardless of the stiffness / damping coefficient of the shocks (...
is the damping coefficient; and and represent the velocity and acceleration of the component, respectively. Along with the standard components, several other components are introduced in this interface. One of them is the impedance, which is used to create a difference in both displacements and for...
Note that using the derivative block is not recommended to use that might lead to unstable results. Another important point is that the damping coefficient c2 =0, and if c2 =c1, then the system response will become damped otherwise it vibrates for a quite long time. You should adjust...
When performing a structural dynamics analysis, modeling the damping can be an important, and difficult, part of the task. A transient analysis of a vibroacoustic micromirror, with viscous and thermal damping taken into account. Below, you’ll find an overview of what to take into consideration ...

The gain is there to adjust the "strength" of the one-way brake as a large damping coefficient. It's not what makes the wheel move. The force (PS Step) applied on the rectangular joint (i.e. on that shaft) is what pushes things forward. Then the frictio...
