Experimental investigations of a walnut tree multimodal dynamics

摘要

Experimental data on the frequencies of a walnut tree are presented. These are derived fromseveral kinds of tests using protocols that are commonly used in vibration analysis: pull andrelease test, hammer impact tests and wind excitation test. The results from these experimentsare then used to validate an analytical approach based on the allometry of the tree. This is madepossible by a detailed digitization of the tree geometry.
