Abstract

In order to obtain an accurate dynamic finite element (FE) model of a radial gate, a rapidly modeling method based on combining Isight-MSC Patran/Nastran simulation and Eigen-sensitivity optimization was proposed.The main idea was that under the condition of ensuring the radial gate’s geometric features and its dynamic characteristics being consistent, mass redistribution is realized through combined calling software to derive the corresponding dynamic FE model.Here, the perturbation method was used to establish the target model for the main frame of the radial gate, and prove the validity of this method through iteration and approaching using the Eigen-sensitivity optimization method.Furthermore, through comparing this method with existing parametric optimization methods, it was shown that the proposed method can be used to get a more precise FE dynamic analysis model under the condition of guaranteeing the minimum variation.Using this approach, a dynamic FE model was constructed according to the actually measured data for the full hydro-elastic model of a radial gate.Example calculations showed that the proposed method needs fewer iteration steps to realize accurately modeling.
