Abstract

This paper presents a comprehensive study between accelerometer, laser vibrometer and microflown probe measurements aimed at comparison of modal model quality assessment. Object of an investigation was a large composite fuselage panel. An extensive test campaign was performed with application of SIMO, MIMO, random and harmonic excitation, velocity and acceleration sensors, contact and non-contact measurement techniques. Advantages and disadvantages of applied instrumentation are discussed taking into account test data variability and the trade-off between workload and test data quality. Presented are real-life measurement problems related to the specific set up conditions. Finally a statistical analysis of estimated models is evaluated to bring to light general assessment of test campaign. Such assessment has a vital importance of successful fault detection based on modal parameters observation as well as in uncertain non-deterministic numerical model updating.
