Drive-Based Vibration Damping Control for .

Abstract: The objective of this letter is to propose a drive-based control method for damping joint vibrations in order to improve the machining quality and the productivity of robot machining. The machining quality is significantly determined by the transfer behavior of the gearboxes installed in the robot joints. This letter presents a novel approach for drive-based damping of these ...

Autodesk Inventor FEA Cantilever Vibration. Vibration (Modal Analysis) Modal analysis in FEA looks similar to static analysis except there are no forces! Because there is no damping, the tinyest oscillating force (at the critical frequency) might vibrate the object to destruction. So Inventor is not looking at forces and stresses, but vibration frequencies. It finds the different vibration ...

Vibration - Wikipedia

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point.The word comes from Latin vibrationem ("shaking, brandishing"). The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.. Vibration can be desirable: for example, the motion of a tuning fork, the reed in a woodwind instrument or ...

Vibration and Sound Damping in Polymers

sion of vibrations/sound through different materials such as metals and polymers. Viscoelasticity and glass transition are two important factors which influence the vibration damping of polymers. Among polymers, rubbers exhibit greater damping capability compared to plastics. Rubbers reduce vibration and sound whereas metals radiate sound.

Because there is no damping, the tinyest oscillating force (at the critical frequency) might vibrate the object to destruction. So Inventor is not looking at forces and stresses, but vibration frequencies. It finds the different vibration modes, which are the different ways the thing can vibrate). So vibration analysis is called modal analysis.

Vibration Damping -

30.01.2015 · Sorbothane is a great solution for vibration damping. Vibration damping is a term that's used in industrial, electronic and ergonomic applications when there is a need to reduce the amount of energy that's produced by the system. Normally engineers try to address and reduce this energy at its source so the disturbing force is not at or near a natural frequency.
