| Abstract: | For particle size measurement by ultrasonic attenuation spectroscopy, an improved harmony search algorithm is proposed. When the harmony search algorithm iteration reaches 200 times, the BFGS algorithm is added to adjust the global and local search capabilities of the harmony search algorithm to improve the convergence accuracy of the algorithm. Numerical simulation of the particle system subject to three typical particle size distribution functions, the improved algorithm inversion shows that deviation of the parameter values are less than 10%.Simultaneously, the experimental ultrasonic attenuation spectrum inversion of the two silicon-water suspension samples with the improved algorithm, compared with nominal size, the deviation are 6.0% and 8.2%.It is feasible to characterize particles with improved algorithms. |
