Abstract:
      A correction factor based on the wave length is developed for the hybrid FE-SEA point junction.At present the modeling of hybrid point junction is mainly based on the hypothesis of infinite structures, without considering the boundary effects to the modeling and analysis results.In this paper, the modeling method of hybrid point junction of plate is presented, then on the basis of dynamic characteristic in the structures, a correction factor is proposed with the benchmark of identification circles.The simulation results demonstrate that the technique proposed in this paper could estimate the influences of boundary to the point junction effectively and improve the modeling precision of hybrid point junction.
