Abstract

Real time substructuring is an approach which couples numerical models and physical structures in a real time experimental test. This can be a beneficial technique for several types of applications where neither full experimental tests nor full simulations are applicable. This contribution tries to make use of decoupling techniques inspired by dynamic substructuring (e.g. FIBS) in real time testing. In this study an experimental test rig (denoted as AB) is considered which consists of substructure A and substructure B. Substructure B is the specimen, which needs to be tested in the real time test as it is hard to model. Substructure A is an so called transmission simulator and is replaced in the real time test by the numerical substructure C, such that the system CB is emulated. The approach can help to reduce the control effort and to include more realistic interface dynamics in the test.
