Optimization of broadband transducer designs by use of statisticaldesign of experiments

摘要

Optimizing designs that involve several parameters is anmultidimensional problem, and the optimum setting of one parameter mayndepend on the exact setting of other parameters. Statistical design ofnexperiments is a powerful methodology to efficiently find the optimumnoperating points, especially when interactions between terms isnimportant. Here, the methodology will be described and applied to antransducer design problem to optimize bandwidth and impulse response.nThe design problem involves four interactive factors, the acousticnimpedance of the first and second matching layer, and the appropriatenthicknesses of the first and second matching layer
