| 摘要: |
| 螺栓法兰连接广泛用于各种工业结构中,为准确预测该连接在实际工作中发挥的作用,需要建立准确高效的有限元模型。针对有限元建模过程中模型各种参数的确定问题,综合使用数值仿真手段和试验手段分别对模型网格参数和接触参数的确定开展研究。参数确定后的螺栓法兰连接结构有限元模型在保证计算精度的前提下,计算效率得到显著提高。 |

| Abstract: |
| Bolted flange joint is widely used in most kinds of industrial structures. In order to indicate the static or dynamic response accurately, an exact and efficient finite element model needs to be built. For the parameters are not certain when building the model, the numerical simulation and experiment were synthetically employed to study the determination of the model′s mesh parameters and contact parameters. After confirming the parameters, the finite element model of bolted flange not only has high computational accuracy, but also has ideal computational efficiency. |
