| 中文摘要: |
| 采用有限元分析软件ANSYS对铁基SMA防松螺母的防断机理进行了研究，建立了参数化的螺栓连接有限元计算模型，并与普通螺栓连接进行了对比分析。研究结果表明：这种新型螺母具有很好的变形协调性，并有效地降低螺纹联接受力较大的第一、二螺纹牙处的应力水平。 |
| 英文摘要: |
| The anti breaking mechanism of Fe based SMA locknut is analyzed and studied by the finite element software ANSYS，the parameterized finite element calculation model of the load distribution in the newly designed bolt connection is established based on the comparison with the ordinary bolt connection. The results show that the new type of nut has the better deformation compatibility, and the stresses of the first and second screw thread in the bolt connection are effectively reduced. |
