Abstract

This paper describes the development of a new dynamic testing technique for structures, in which a physical test of a critical substructure is coupled in real time to a numerical model of the remainder of the structure. Results are presented from several different experiments in which the physical substructure test is coupled to a linear numerical model of the remainder. The results are compared with those from structural analyses and with the output of a detailed numerical simulation of the entire system, including actuator and control system dynamics. The system is shown to behave in a controlled way and is regarded as a significant step forward from conventional pseudo-dynamic testing. The system is currently being extended to allow control of many degrees of freedom, and to incorporate non-linear behaviour into the computer model.
