MODELLING AUTOPARAMETRIC RESONANCE IN A COUPLED PENDULUM OSCILLATOR SYSTEM USING HYBRID TESTING

摘要

Hybrid testing is a novel form of system modelling which consists of a model which is part numerical, pan experimental. This form of testing has applications in the automotive, aerospace and construction industry where it is being developed as an advanced form of component testing. In this paper we present results from a hybrid numerical-experimental system of a coupled pendulum oscillator system. This system is a good test case example for developing the science of hybrid testing because it has clearly defined linear and nonlinear pans. We show how such a system can be modeled by coupling an experimental pendulum with a numerical oscillator. We include discussion on delay effects, control techniques, accuracy and stability of the system.
