摘要:
采用有限元数值求解方法,对由圆柱销钉和匀质正交各向异性层合板构成的连接结构模型进行了销钉拔出过程中接触面的应力计算与分析模型计算分两个载荷步进行:载荷步一进行不加外载时结构过盈配合所致预应力的计算；载荷步二进行施加位移载荷使销钉从板中拔出的应力计算.结果表明:应力集中在销钉和孔边附近,且呈现对称分布趋势；其中孔径向和环向方面应力值变化幅度较大,最大应力出现在连接板孔边上,孔中心轴向方向应力值变化幅度较小,最大应力在销轴上,为预测销钉拔出造成的易损伤位置提供参考依据,同时应力计算结果为进行各向异性连接件的失效损伤分析奠定了基础.
Abstract:
The connection interface stregses of pin joint composed of a cylinder pin and homogeneous orthotro.pic laminate are calculated and analyzed with finite element method when the pin is pulled from the laminatehole. The model is caleulated by two steps : firstly ,ealeulating pre-stresses caused by assembly interference ofpin and plate without external loads; secondly, calculating stresses when pulling pin from the laminate resultedfrom applying displacement load. The final results show that stresses are concentrated near the pin and holeedge and display symmetrical distribution. Stresses in the radial and tangential directions change much and themaximum happens on the laminate hole edge, while stregses in the axial direction of hole centre change littleand the maximum exists on pin surface, These can offer reference for predicting regions where damages mostpossibly occur and lay the foundation for analyzing failures of orthotropic laminate.
