During radial–axial ring rolling process, cooperative strategy of the feed is critical for dimensional accuracy and thermo mechanical parameters distribution formed ring. In order to improve comprehensive quality parts, response surface method (RSM) employed first time optimize process by combining it with an improved verified 3D coupled thermo-mechanical finite element model. The trajectory put forward describe relationship three variables are designed based on trajectory. achieve...
Underwater acoustic imaging employs a special form of array which includes numerous transducer elements to achieve beamforming. Although large-scale can bring high resolution, it will also cause difficulties in hardware complexity and real-time application. In this paper, order reduce the number elements, sparse optimization for Mills cross is proposed, considering elements’ distributions weights design. The improved genetic algorithm adopted generate evolutions solution. ensure effective...
Holographic reconstruction is an inversion method with which the sound radiation characteristics of source can be reconstructed by using nearfield acoustic holography. In this paper, field holographic researched based on model Using MATLAB and LabVIEW virtual instrument software platform, integrated system designed implemented. The functions include sensor array calibration, signal acquisition processing, reconstruction, results visualization. performance presented was tested experiments in...
Suppression of grating lobes caused by spatial aliasing should be considered in array design for underwater acoustic imaging. To address this problem, a different approach to beamform with nonsinusoidal signal suppression is proposed paper. The desirable can obtained exacting the envelopes received signals. reception short time duration identical weak detection and matched filtering employed enhance signal-noise-ratio (SNR). And then beamforming domain investigated. As envelope nonperiodic,...
As the common configuration of hydrophone, thin-walled piezoelectric tubes develop two different modes, namely 31 mode and 33 mode. Their behaviors performances are studied, especially their receiving characteristics. A comparison about sensitivity between case presented based on elastostatic theory finite element method. The approach to obtain voltage response in analysis is introduced according electroacoustic reciprocity formula. Some hydrophone prototypes 31-mode 33-mode thin- walled...
