复合材料结构广泛采用机械连接。由于孔轴配合中存在间隙,影响多孔连接的内力分配和接头强度。螺栓连接的过盈配合和铆钉连接都能消除间隙,但这样就造成孔轴相互挤压,因而引起应力,并可能造成局部损伤。本文探讨层板双孔过盈配合引起的应力,及讨论过盈配合应用的可能性。 Composite structures are widely used mechanical connections. Due to the gap in the hole-shaft fit, the internal force distribution and the joint strength of the porous joint are affected. The interference fit and the rivet connection of the bolt connection both eliminate the gap, but this causes the hole axes to be pressed against each other, thereby causing stress and possibly causing partial damage. This article explores the stresses caused by double-hole laminate interference and discusses the possible application of interference fit.
