A Benchmark Test Structure for Experimental Dynamic Substructuring
In this paper a benchmark test structure for experimental dynamic substructuring is presented. The benchmark is a simple structure designed to gain insight into difficulties experienced in experimental dynamic substructuring (DS). First a brief introduction of dynamic substructuring is presented, followed by a summary of current bottlenecks in experimental DS. From these difficulties a set of requirements for the benchmark is formulated. Thereafter the design is presented and its numerical model is validated by a measurement on the fabricated benchmark. Finally a DS analysis is performed on the benchmark structure to show it’s ability to quickly verify or falsify a DS analysis.
