TL;DR: In this paper, a vibrational damping means is used to reduce or eliminate the vibrations of the stylus of a measuring probe mounted on a machine, and which are transmitted to the probe stylus via the machine quill and probe body.
Abstract: Vibrations of the stylus (4) of a measuring probe (1) mounted on a machine, and which are transmitted to the probe stylus via the machine quill and probe body, are reduced or eliminated by a vibration damping means positioned within a cavity of the stylus. FIG. 2 illustrates a first embodiment in which the vibration damping means is a unconstrained rubber cylinder (16), in a hollow cartridge (12) connected to the stylus at its tip. Alternatively a dynamic vibration absorber can be used.

TL;DR: In this paper, a single-span two-disk rotor bench was built to simulate the starting process of a rotor, and a new Rotor dynamic vibration absorber (RDVA) was designed and installed in the middle of the rotor.
Abstract: The serious vibration of rotors around the critical speed is a problem in rotor systems To overcome this problem, a single-span twodisk rotor bench was built to simulate the starting process of a rotor A new Rotor dynamic vibration absorber (RDVA) was designed and installed in the middle of the rotor A on-off control method based on speed was applied to control the on-off position of the electromagnet in RDVA Therefore, the natural frequencies between two selected values could be changed The principles for the vibration control of the rotor system were studied The vibration suppression performance of an RDVA is a function of its location The location of the RDVA is subject to several constraints due to the compact structure of the rotor system As a result, RDVA cannot always be installed at the optimal location of vibration suppression Accordingly, a study was performed to observe the effect of RDVA location on the vibration suppression performance Results showed that installing RDVA with on-off control between the two disks not only suppressed the violent vibrations of the rotor at critical speed during the starting process but also avoided the two resonance peaks generated by the traditional absorber RDVA maintained the vibration of the rotor at a low level in the entire speed range Furthermore, the vibrations of the rotor system decreased by 20 % when RDVA was installed near the rotor support
