effects on short pitch rail corrugation growth of a rail Vibration Absorber damper
Wear, 2011Co-Authors: T X WuAbstract:Abstract Rail corrugation growth is related to the wheel–track dynamics and uneven wear on the rail head. The so-called pinned–pinned resonance of track Vibration is considered as the cause of short pitch rail corrugation that is associated with railway rolling noise generation. A promising measure for reducing railway rolling noise is by the use of rail Vibration Absorber/damper. Reduction of 5–6 dB in the rail radiated noise can be achieved using rail Vibration Absorber/damper. In addition a rail Vibration Absorber/damper is found to be able to suppress the pinned–pinned resonance, and thus, its use may lead to attenuate formation of short pitch rail corrugation. In this work the effects of rail Vibration Absorber on short pitch rail corrugation growth are studied by combining the wheel–track-Absorber dynamics, rolling contact mechanics and wear. The evolution process of rail corrugation is simulated and the results show that short pitch rail corrugation, whose wavelength is associated with the pinned–pinned resonance, is effectively suppressed by a rail Vibration Absorber. The use of rail Vibration Absorber has both immediate and long term effect on the railway rolling noise control, i.e. reducing the rail radiation and attenuating growth of short pitch rail corrugation, respectively.

design of a dynamic Vibration Absorber against Vibrations in turning operations
Journal of Materials Processing Technology, 2001Co-Authors: C Y Nian, Y S TarngAbstract:Abstract A dynamic Vibration Absorber is mounted on a cutting tool against Vibrations in turning operations. It is shown that the dynamic Vibration Absorber can reduce the magnitude of the frequency response function of the cutting tool. As a result, Vibrations can be effectively suppressed in the cutting process when the dynamic Vibration Absorber is attached to the cutting tool. Experimental results performed in turning operations are presented to illustrate this approach.

Chatter suppression in turning operations with a tuned Vibration Absorber
Journal of Materials Processing Technology, 2000Co-Authors: Y S Tarng, J. Y. Kao, E.c. LeeAbstract:In this paper, a piezoelectric inertia actuator is mounted on the cutting tool and acted as a tuned Vibration Absorber for the suppression of chatter in turning operations. It is shown that the tuned Vibration Absorber can modify the frequency response function of the cutting tool so as to improve cutting stability in turning operations. Chatter can then be effectively suppressed due to the increase of cutting stability. Theoretical studies and experimental results performed in turning operations are presented to illustrate this approach.

Application of Dynamic Vibration Absorber in Torsional Vibration Optimization of Transmission System
2018 IEEE International Conference on Mechatronics and Automation (ICMA), 2018Co-Authors: Sizhong Chen, Lin YangAbstract:Torsional Vibration is an important form of Vibration of vehicle driveline, which can give rise to a variety of complex Vibration and noise problems. In order to study the effect of torsional Vibration of a driving system on the Front-engine Rear-drive(FR) vehicle, the model of the vehicle transmission system is established to describe the torsional Vibration. In order to weaken the torsional Vibration of the transmission system on the natural frequency, a dynamic Vibration Absorber is added to the drive system model. The results show that the dynamic Vibration Absorber has a great effect on the optimization of torsional Vibration of transmission system, and that the dynamic Vibration Absorber can effectively reduce torsional resonance at certain frequencies.
