Title: Membrane-type resonator as an effective miniaturized tuned vibration mass damper

Abstract

Damping of low frequency vibration by lightweight and compact devices has been a serious challenge in various areas of engineering science. Here we report the experimental realization of a type of miniature low frequency vibration dampers based on decorated membrane resonators. At frequency around 150 Hz, two dampers, each with outer dimensions of 28 mm in diameter and 5 mm in height, and a total mass of 1.78 g which is less than 0.6% of the host structure (a nearly free-standing aluminum beam), can reduce its vibrational amplitude by a factor of 1400, or limit its maximum resonance quality factor to 18. Furthermore, the conceptual design of the dampers lays the foundation and demonstrates the potential of further miniaturization of low frequency dampers.

  • Values of the effective mass B2 and the stiffness parameter C2 for quadrupole vibration of even?even spherical nuclei have been computed from the B (E 2) values and energies of first 2+ states adopted by Stelson and Gredzins. A comparison of these with values predicted by a liquiddrop model shows B2 an order of magnitude larger than the predictions. The value of C2 is usually less than the prediction but at magic numbers is many times greater.
  • Triple layer SiO{sub 2}/AlN/SiO{sub 2} composite thin film bulk acoustic wave resonators (TFBARs) were studied for applications in atomic clocks. The TFBAR's were tuned to 3.4 GHz, corresponding to half the hyperfine splitting of the ground state of rubidium {sup 87}Rb atoms. The quality factor (Q) was equal to 2300 and the temperature coefficient of the resonance frequency f{sub r} amounted to 1.5 ppm/K. A figure of merit Qf{sub r} of {approx} 0.8 x 10{sup 13} Hz and a thickness mode coupling factor of 1% were reached. Such figures are ideal for frequency sources in an oscillator circuit that tracksmore » the optical signal in atomic clocks.« less

  • Oil and gas well drilling under difficult conditions and the drilling of horizontal sections of oil wells impose new requirements on the components of the drill-string bottom assembly (DSBA). One such requirement is longitudinal stability of the DSBA in the case of action of optimal loads. With limited dimensions of the transverse section of the well, this can be achieved only by reducing the length of the DSBA. One of the elements of the DSBA is the bottom-hole vibration damper. In current practice, the DSBA is made up with drill vibration dampers that are quite long, designed for a specificmore » load. This makes it difficult to use vibration dampers in DSBA intended for drilling under difficult conditions; also, this limitation makes it necessary to stock a greater number of different vibration dampers. In order to eliminate these problems, a bottom-hole vibration damper with a sheathed variable-rigidity elastic element was developed that has been tested successfully in oil fields of the Ukrneft` Production Association. The field tests not only confirmed the reliability and effectiveness of operation of these vibration dampers under difficult drilling conditions, but also pointed out ways in which they could be improved.« less
  • In this paper, results of experimental rotordynamic evaluations of a novel, high load chambered porous damper design are presented. The chambered porous damper concept was evaluated for gas turbine engine application since this concept avoids the nonlinearities associated with high-eccentricity operation of conventional squeeze film dampers. The rotordynamic testing was conducted under large steady-state imbalance and simulated transient blade-loss conditions for up to 0.254 mm (0.01 in.) mass c.g offset or 180 g-cm (2.5 oz-in.) imbalance. The chambered porous damper demonstrated that the steady-state imbalance and simulated blade-loss transient response of a flexible rotor operating above its first bending criticalmore » speed could be readily controlled. Rotor system imbalance sensitivity and logarithmic decrement are presented showing the characteristics of the system with the damper installed. The ability to accommodate high steady-state and transient imbalance conditions makes this damper well suited to a wide range of rotating machinery, including aircraft gas turbine engines.« less
