| 摘要:采用ANSA和ANSYS联合对某低速机贯穿螺栓进行建模仿真，探讨了不同工况下，该贯穿螺栓的应力水平和应力幅值变化。结果表明:各贯穿螺栓由于安装位置不同，所受应力幅值也不尽相同；并呈现两端大，中间小的特点。为贯穿螺栓的优化设计提供了参考。 |

| Abstract:Both ANSA and ANSYS were used in the modeling simulation of the through bolt of a low speed engine. The stress level and stress under different working condition, and the stress and amplitude change of the through bolt was discussed under different working condition. The results show that the stress amplitude of the through bolt changes due to different assembly position, and it is big at both ends and small in the middle. The research results offer reference for optimal design of through bolts. |
