Title: Glass-Specific Behavior in the Damping of Acousticlike Vibrations

Abstract

High frequency sound is observed in lithium diborate glass, Li{sub 2}O-2B{sub 2}O{sub 3}, using Brillouin scattering of light and x rays. The sound attenuation exhibits a nontrivial dependence on the wave vector, with a remarkably rapid increase towards a Ioffe-Regel crossover as the frequency approaches the boson peak from below. An analysis of literature results reveals that the boson-peak frequency is closely related with a Ioffe-Regel limit for sound in many glasses. We conjecture that this relation, specific to glassy materials, might be rather common among them.

  • In the operation of settling screw centrifuges, free vibrations may induce pulsation of the moment, which in turn triggers the protective mechanism of the reduction gear at a performance far below the theoretical one. With the aid of a diagram the author describes the construction and operation of a screw centrifuge with a damping device, and he sets forth equations whereby he can analyze the amplitude and frequency of such vibrations. He then calculates the optimum parameters of effectiveness for a damping device and establishes a sequence of calculation for the design of such a device.
  • In planning destructive impact devices, there is definite interest in finding the parameters of a vibration which is transferred to the manipulator during the operation of the inpact mechanism. In this paper a method is proposed for determining the parameters of the force action of the impact mechanism on the manipulator in a general boundary regime, with a spring vibration absorber between them.
  • Deep inelastic reactions, are studied including both particle transfer and excitations of collective surface modes. Detailed results are given for three examples.
  • A new, active damping system eliminates ``stick/slip`` torsional drillstring vibrations. The system controls the energy flow through a hydraulic topdrive and makes it react as a vibration damper. The control algorithm is programmed in the electronic control system for the pump unit of the topdrive. Field testing of the system took place in a deep exploration well, where it contributed to excellent coring performance.
