Genetic-Algorithm-Based Procedure for Pretest Analysis

摘要

THE optimization of the test setup in experimental modal analysis, the so called pretest analysis, is important to allow the execution of vibration tests on large structures. To reduce measurement time and cost, the test has to be performed using the least number of sensors and shakers that will identify the structural modes in the measured frequency range.' This paper issues the optimal layout of sensors for experimental modal testing as a testbed for using genetic-algorithm (GA)2-based procedures in the solution of sensors and actuators optimal placement for adaptive structures design.
