The goal of this study is to dynamically simulate a turning-centre main spindle system utilizing the systems receptance coupling technique determine system's first three resonant frequencies in event transverse vibrations. findings are then confirmed using finite element ANSYS software. significance analysing described that it can be utilized optimize terms resonance for improved performance vi...
We measure electron tunneling in transistors made from C(140), a molecule with a mass-spring-mass geometry chosen as a model system to study electron-vibration coupling. We observe vibration-assisted tunneling at an energy corresponding to the stretching mode of C(140). Molecular modeling provides explanations for why this mode couples more strongly to electron tunneling than to the other inter...
C/SiC composite material is the best choice for important parts such as hot-end structure of aerospace vehicles. Research and optimization cutting force ultrasonic vibration-assisted grinding are great significance when it comes to revealing machining mechanism composites realizing low-damage efficient machining. In this paper, comparative experimental study common carried out; variation laws r...
We measure electron tunneling in single-molecule transistors made from C140, a molecule with a mass-spring-mass geometry chosen as a model system to study electron-vibration coupling. We observe vibration-assisted tunneling at an energy corresponding to the stretching mode of C140. Molecular modeling provides explanations for why this mode couples more strongly to electron tunneling than the ot...
We perform 2D Molecular Dynamics simulations of sheared granular layers in the presence of applied vibration. A primary goal is to understand the physics of dynamic earthquake triggering. We adopt a mesoscopic measure of non-affine deformation for characterizing the granular dynamics during slip without or with applied vibration. Our results show that the onset of non-affine strains correlates ...
In Electrical Discharge Machining, oxides (or debris) are created and accumulated in the sparking gap between an electrode and a work piece. If the debris density becomes too great in certain points in the gap, there is a reduction in the resistance, which encourages the formation of abnormal discharges, results in significant electrode damage and slows down the material removal rate. To enhanc...
Heterodyne holography is an extremely versatile and powerful holographic technique that is able to fully control the amplitude, phase and frequency of both the illumination and holographic reference beams. Applied to vibration analysis, this technique is able to detect the signal of the carrier or the one of any vibration sideband. A complete analysis of the vibration signal can thus be made, a...
