Title
Modelling of sprayer boom motion by means of output-only maximum likelihood identification techniques
Author
Abstract
Output-only modal analysis allows the estimation of modal models for structures in their real in-operation conditions. One of the main drawbacks of this approach is that the operational mode shape estimates remain incorrectly normalized (dependant on the unknown level of excitation) what somewhat restricts the applicability of in-operation modal models. Until recently, no techniques were available for the normalization of operational mode shapes purely based on experimental output-only data. Recently, a sensitivity-based normalization approach, that can be used for output-only data, was proposed and successfully tested. This contribution compares the results of 'input-output and output-only modal analysis experiments performed on a tractor-sprayer combination. The sensitivity-based normalization approach was experimentally validated by comparing the results to the driving point normalization method.
