| 中文摘要: |
| 针对混合FE-SEA点连接建模提出了一种基于波长的点连接修正因子。目前混合点连接建模主要基于无限结构假设,未考虑边界因素对建模和分析结果的影响。本文首先基于波动理论建立了无限板结构的混合点连接模型,然后根据板结构系统的动力学特性,提出了以判定圆为基准的点连接修正因子。仿真结果表明,本文提出的混合点连接修正因子可有效估计边界对点连接的影响,改进了混合点连接建模的精度。 |

| 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. |
