| 摘 要： | 通过有限元分析与理论推导,系统研究了应力集中、残余应力、预紧力对复合材料干涉配合接头疲劳寿命的影响。研究结果表明复合材料干涉配合接头的有效应力集中系数小于复合材料间隙配合接头的有效应力集中系数;复合材料干涉配合接头在配合部位具有较高的残余压应力;预紧力对整个接头的有效应力集中系数有一定缓解作用,随着预紧力的增大复合材料板上的应力集中系数有缓慢减小趋势。 |

| Abstract: | Making use of Finite Element Method, experiment and academic analysis, the influence of stress concentration, residual stress and preload on fatigue life of interference-fit composite joint were studied. The result shows the following important points. The notch coefficient of interference-fit composite joint is less than the notch coefficient of sliding-fit composite joint; there is upper residual compressive stress at assort position of interference-fit composite joint; preload redound to remit notch coefficient of interference-fit composite joint; in company with the aggrandizement of the preload, the stress concentration factor of composite has slowness wane. |
| Keywords: | Finite Element Method composite materials interference-fit strengthen method |
