摘要
通过有限元参数分析研究了影响螺栓连接铝合金T形受拉接头撬力的一些因素,包括:T形件翼缘厚度,预紧力的大小,T形件及螺栓材料,边距系数大小.通过分析有限元计算结果,研究了这些因素对撬力大小的影响.
This paper analyzes the effects of the thickness of the flange, the preloading of the bolt, the material characteristics of the bolt and T-stub and the margin coefficient which connected with the tensile performance of the T-stub closely. The analysis is developed by means of finite element method simulation with finite element program/kNSYS. Finally, based on the result of finite element analysis, the effects of all the parameters are analyzed.
