چکیده
experimental methodology is developed to accurately measure the effective radii of unfwused, circular plane piston transducers. The transient and steady-state relations [ 11 for the various maxima and minima diffraction concepts described by Lord are also used to propose an extension of the definition of the A " E M A pulse intensity integral to properly analyze cw and tone burst data. Using an exact theory of Beissner an The unfocused circular plane piston effective radius can be determined accurately from transducer axial pressure extremum z, measurements using the known

The Arccos and Lommel Diffraction an Approximate Fourier Transform Pair Leading to a Unified Theory of Spatially Averaged Diffraction Corrections for Ultrasonic Piston
This work has three goals. The first is to derive closed-form spatially averaged two-way diffraction corrections for focused piston transducers operating in pulsed mode. The goal is attained by (i) establishing that the arccos and Lommel diffraction formulations form an approximate Fourier transform pair and (ii) exploiting this newly established Fourier equivalence in rigorous and original der...
متن کاملElastic Wave Diffraction of a Piston Source and Its Effect on Attenuation Measurement
The radiation of an elastic wave field from a plane piston source is formulated using the representation theorem, in which the Green's function for an elastic half space is employed. On the basis of this formulation, we derive the radiated elastic wave field for both compressional and shear wave sources. We study the diffraction of elastic waves incident on a receiver that is coaxially aligned ...
متن کاملExperimental Study on the Influence of the Rotating Cylinder Block and Pistons on Churning Losses in Axial Piston Pumps
Pressure and performance requirements of axial piston pumps and the proportion of churning losses in axial piston pumps increase significantly with increasing speed. To investigate the primary distribution of churning losses in axial piston pumps at various ranges of speed, a test rig was set up in which other friction losses can be eliminated, thus making it possible to investigate the net chu...
متن کاملMultichannel phase-shifted interferometer.
A new real-time interferometer based on diffraction phenomena is discussed. It consists of a point-diffraction interferometer fabricated on a transmission grating. The real-time data-analysis capability is achieved by simultaneously introducing a phase shift (piston) on the three separate channels of diffracted interferograms. Mathematical analysis and preliminary observational results are incl...
