Summary: | 碩士 === 國立海洋大學 === 造船工程學系 === 86 === FRP管榫條式接合,是將一條狀榫條,插入由管材鐘口管和插口管上
榫條溝槽所構成的通道內,而達到接合的目的,當接頭承受一軸向力時,
榫條接合部份會產生極大應力,因此對於接頭榫條接合部份需要做一受力
後破壞模式的分析。 本文主要是使用有限元素分析軟體ANSYS,對於此
項榫條式接頭進行彈塑性分析,首先由拉力試驗取得所需的接頭材料性質
,然後改變一些參數,包括榫條截面高度和寬度以及管材間的間隙,於
ANSY中分別建立模型進行分析,針對分析結果,加以評估比較,分析結果
可做為日後接頭加工及設計時的基本參考。 由ANSY分析後的應力分
佈情形,可以瞭解接頭的破壞模式,發現會在榫條鐵氟隆部份受到嚴重的
擠壓,並且產生遠久變形的破壞模式。
Locking joint is realized by inserting a cable which blocks
the bell to the spigot on the sleeve to the FRP pipe. This block
transfers the axial stresses along the pipes and therefore it
requires very high mechanical characteristics, so we must
perform a fracture analysis of Locking joint of the FRP pipe.
The analysis is performed by using the software package of a
Finite Element Methods, ANSYS. First, find the material
properties of the coupling by tension test, then change the
height and width of key lockcross section to establish the
model. It has great advantages to design aLocking Coupling by
performing a preliminary analysis. After performing the ANSYS
analysis, we can find the fracture mode of the coupling, which
is the permanent deformation in theTEFLON key lock.
