The effects of internal resonances in vibration isolators under absolute velocity feedback control
, 2007 Conventional vibration isolators are usually assumed to be massless for modelling purposes, which tends to overestimate the isolator performance because the internal resonances (IRs) due to the inertia of the isolator are neglected.

Nonlinear Soil Response in the Near-Field of a Vibrator Truck: Application to Land Seismic Surveys [PDF]
, 2007 The nonlinear behavior of soils can significantly modify the wavelet radiated from vibrator trucks. In this paper, we describe a field experiment designed to measure the nonlinear response of a natural soil formation in the near-field of a vibrator ...

Beam vibration studies using measured bending wave impedance [PDF]
The Journal of the Acoustical Society of America, 1994 Acoustic impedance in a plane-wave field is obtained experimentally using the well-known two-sensor technique. Recently, in the literature, the application of this technique to determine bending wave impedance has been demonstrated. In transverse vibration, the impedance is defined in terms of force and moment and the corresponding linear and angular ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing
Advanced Engineering Materials, EarlyView.This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

DEVELOPMENT OF FUNDAMENTAL THEORY OF THIN IMPEDANCE VIBRATORS
Progress In Electromagnetics Research M, 2016 In the paper, we prove two theorems relating to the theory of thin impedance vibrator radiators excited by a lumped voltage generator under rather general conditions. The first theorem proves that influence of external electrodynamic media on the vibrator current distribution is limited and can be estimated using a small natural parameter.

Measurement of Biomechanical Impedance - Its device and measuring conditions [PDF]
, 1988 Biomechanical impedance is relatively small compared to industrial mechanical impedance. Thus it is difficult to measure it precisely. A biomechanical impedance measuring system was developed for portable use by means of random excitation.
