钢齿齿长变化对复合材料预紧力齿连接接头力学性能影响的试验研究
Experimental Ressearch on Mechanics Properties of Composite Pre-tightened Teeth Connection Based on Length Changes of Steel Teeth
摘要
Abstract
The CFRP pre-tightening teeth connector were investigated by changing the length of steel teeth,and the failure modes and the ultimate load of the specimens were tested.In addition,the critical tooth lengths of bending shear deformations were put out through deducing equations and the-oretical analyses.The research shows that the specimens have three failure modes when the lengths of steel teeth were changed.It may effect the ultimate bearing capacity of single tooth when the length of steel tooth is small .However,the influences tend to be stable when the steel tooth achieves a certain length.Critical tooth length may be calculated and the result is j ust the designed length of the steel tooth.关键词
