| 摘要: |
| 为分析几何参数对螺栓法兰连接刚度的影响，用MSC.Patran软件的二次开发工具PCL（Patran Command Language）建立了螺栓法兰连接的参数化模型。研究了螺栓法兰连接刚度随连接结构几何参数的变化规律并进行了灵敏度分析。经分析可知，连接结构刚度对开孔位置比例参数最敏感，其次是上法兰厚度。当上部段长度大于某一数值时，连接结构刚度对上部段长度参数不敏感，这一结论能为连接结构动力学简化建模提供一定理论参考。 |

| Abstract: |
| In order to analyze the effects of geometric parameters on the stiffness of bolted flange joint, a parameterized model of bolted flange joint was constructed by using PCL (Patran Command Language) on the platform of software MSC.Patran. The law of the stiffness of bolted flange joint with the change of geometric parameters was studied, and the sensitivity of geometric parameters was analyzed based on the parameterized model. The results show that the ratio of the location of hole is the most sensitive factor to the stiffness of bolted flange joint, and the next one is thickness of upper flange. When the length of upper body is up to a const, the stiffness of bolted flange joint is insensitive to the length of upper body, and this conclusion can provide a reference to simplify the dynamic model of joint. |
