A real-time simulation method for cantilevered beam is presented. In this method, a point load acting on deforming cantilevered beam is estimated in real-time by using the Kalman filter, and the deformation of cantilevered beam is simulated by using estimated point load at the same time. The Kalman filter is widely known as the method which estimates uncertain parameters utilizing both numerical model and experimental data in sequential processing. And the parameters estimated by above-mentioned method can be strong likelihood for actual phenomenon included in analysis object. But operating Kalman filter needs to make the suitable state space model for analysis target. In this study, a simple experiment is conducted to verify the effectiveness of real-time estimation and real-time simulation for deforming cantilevered beam by using the Kalman filter and strain measurement. Experimental results show that the real-time estimation and real-time simulation are operated satisfactorily with deformation of cantilevered beam under the particular configuration of the Kalman filter.
