Beamlike dynamic vibration absorbers [PDF]
The Journal of the Acoustical Society of America, 1981 Although the concept of the dynamic absorber and its potential for vibration reduction were first discussed in the early part of this century, John Snowdon's comprehensive work in this area was certainly a pioneering effort. By rephrasing the standard equations in terms of complex dynamic moduli, it became possible to treat viscoelastic (rubberlike ...

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Vietnam Journal of Mechanics, 2015 In practice, an inverted pendulum can be used to model many real structures as the arms of robots, soil structures, or fluid structures. However, the study on the design of dynamic vibration absorber for inverted pendulum structures is very limited in ...

The Experimental Performance of a Nonlinear Dynamic Vibration Absorber [PDF]
, 2013 This paper investigates the physical behaviour and effectiveness of a nonlinear dynamic vibration absorber (NDVA). The nonlinear absorber considered involves a nonlinear hardening spring which was designed and attached to a cantilever beam excited by a shaker. The cantilever beam can be considered at low frequencies as a linear single degree-of-freedom

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

On the Dynamic Vibration Damped Absorber of the Vibration System
Transactions of the Japan Society of Mechanical Engineers, 1977 Main purpose of this paper is to analyse the forced vibration prevention of the vibration system with positive or negative damping by the damped dynamic absorber. The cases treated in this paper are: the case I (the alternative exciting force of a constant magnitude is acting on the mass of the main system), the case II (the alternative exciting force,

Journal of Low Frequency Noise, Vibration and Active Control, 2021 This paper presents a new dynamic absorber attenuating the vibrations at three resonance frequencies simultaneously. The dynamic vibration responses of mechanical systems with dynamic absorbers are mainly influenced by how close the eigenfrequencies of ...
