【摘要】：通过建立胶接接头拉剪强度的有限元模型,预测接头拉剪过程中的胶层内部最大应力,基于胶层和钢板的材料特性、几何因素与胶层内部最大应力的响应面模型,分析了不同因素对胶接接头强度的影响规律.结果表明:胶层内部最大应力与钢板厚度呈负相关关系;胶层厚度和钢板屈服强度均存在使胶层内部应力最小的临界值;胶层内部最大应力与胶层屈服强度呈负相关线性关系,其斜率受到胶层厚度及钢板的厚度和屈服强度的共同影响.
[Abstract]:By establishing the finite element model of tensile and shear strength of adhesive joint, the maximum stress of adhesive layer in the process of tension and shear is predicted. Based on the material characteristics of rubber layer and steel plate, the response surface model of geometric factors and the maximum stress inside the adhesive layer, the finite element model is established. The influence of different factors on the strength of adhesive joint was analyzed. The results show that there is a negative correlation between the maximum stress and the thickness of the steel plate, the critical value between the thickness of the rubber layer and the yield strength of the steel plate, and the negative linear relationship between the maximum stress and the yield strength of the rubber layer. The slope is affected by the thickness of rubber layer and the thickness and yield strength of steel plate.
