Derivation of slamming loads using the Optimal State Estimation Method

This paper shows the use of the Optimal State Estimation Method (OSE) for estimation of slamming forces for model experiments. The OSE estimates the external loads using the response of the model and calculated natural modes. The response is measured with several accelerometers to allowthe OSE to estimate the response of the flexible modes which is needed for an accurate estimation of the external forces. When the calculated natural modes are close to the actual natural modes and with well conditioned measurement signals, the OSE estimates the external force accurately. © 2007 Taylor & Francis Group, London.
