...Kevin Shoyer; Kevin Nakahara; Philip D. Cha In this paper, a properly tuned vibration absorber (spring-mass system) is used to induce a point of zero vibration, or node, anywhere along an arbitrarily supported beam for the purpose of suppressing vibration. Other benefits of enforcing a node include...

...Ji-Hou Yang; Xiao-Dong Yang; Qing-Kai Han; Jin-Guo Liu To improve the vibration reduction effect in low-frequency band of dynamic vibration absorber (DVA), a novel type of articulated silicone gel column (SGC) is introduced in the design of the tuned dynamic vibration absorber. The nonlinear...

...Tsuyoshi Inoue; Ryota Okumura; Shota Yabui; Xiangyu Jiang The torsional vibration hinders the reduction of automobile exhaust gas emitted by using engines with a reduced number of cylinders. Centrifugal pendulum vibration absorbers (CPVA) have been used in engines to suppress torsional vibration...

...Seon Il Ha; Gil Ho Yoon This research presents a pendulum dynamic vibration absorber (PDVA) consisting of a spring and a mass in order to attenuate structural vibrations at two frequencies of hosting structure. It is a convention to attach several dynamic absorbers to hosting structure for the sake...

... variability or nonrepeatability due to jointed interfaces. Inspired by advances in additive manufacturing (AM) and nonlinear vibration absorber theory, this research seeks to redesign jointed structures in an attempt to reduce the nonlinear effects introduced by the jointed interfaces. First, the nonlinear...

...J. H. Porter; P. S. Harvey, Jr. Vibration absorbers are commonly used to reduce unwanted structural vibrations. In this paper, a vibration absorber composed of a sprung mass is used to enforce a location of zero displacement (or node) at a specified location on a Euler–Bernoulli beam under harmonic...

... replicate a mass-spring-damper system to reduce efficient radiating structural modes at low frequencies. The elastic layer typically used has sound absorption properties to create a noise control device with a wide bandwidth of performance. The natural frequency of an embedded dynamic vibration absorber...

...P. W. Wang; C. C. Cheng The purpose of this paper is to introduce a systematic method of designing a vibration absorber that affects vibration attenuation at multiple frequencies. This vibration absorber is a nonprismatic beam with natural frequencies intentionally designed to coincide...
