Experimental investigations of a walnut tree multimodal dynamics
Résumé
Experimental data on the frequencies of a walnut tree are presented. These are derived from several kinds of tests using protocols that are commonly used in vibration analysis: pull and release test, hammer impact tests and wind excitation test. The results from these experiments are then used to validate an analytical approach based on the llometry of the tree. This is made possible by a detailed digitization of the tree geometry.
