| 摘 要： | 基于ANSYSWorkbench软件，采用层单元法和多点约束技术，模拟了盘一盘螺栓连接结构的螺栓预紧力，对其进行了模态分析，并与试验结果进行了比较。研究表明：采用层单元法模拟螺栓预紧力的模态结果与试验结果吻合较好，为在预紧力作用下螺栓连接结构模态频率的有限元计算提供了1种有效方法。

| Abstract: | Based on ANSYS Workbench software, the boh preload of bolted plate-plate structure was simulated by cell elements and multi-point constraint technology. The modal analysis was conducted and compared with experimental results. The results show that the modal results agree well with the experiments. It provides an effective finite element method to calculate bolted joint structure with preloads. |
