Nonlinearity is a frequent occurrence in engineering structures. The nonlinearity detection in the operating mechanical systems is important because the nonlinearity can change the dynamic behaviour. The aim of this work is to experimentally measure the nonlinearity of a flexible beam structure due to the different applied dynamic load configurations. In this study, the modal parameters were obtained from the modal testing. The excitation approach by adopted the burst random excitation through an electromagnetic shaker and the vibration response was measured using accelerometers. The frequency response function (FRF) at different level of dynamic excitation was utilized to exhibits the nonlinear behaviour. The elastic vibration characteristics which are bending and torsional modes were compared to identify the nonlinear. As a conclusion, the results showed that the nonlinear property of the flexible beam is due to the geometric nonlinearity.
