偏心率对空间偏心管状接头应力集中的影响

The Effect of Eccentricity on Stress Concentration of the Spatial Non-Concurrent Tubular Joints

修订了空间管状接头应力分析的计算机程序ＳＡＭＴＪ，使其能用来计算空间偏心管接头的应力集中系数（ＳＣＦ）．然后以偏心ＤＴ型接头为例，计算了可能热点的ＳＣＦ，并探讨了偏心率对ＳＣＦ的影响．

The computer program SAMTJ is revised for stress analysis of non-concurrent spatial tubular joints. Multiplanar DT non-concurrent tubular joints with different eccentricity in the vertical diametrical plane of chord were computed by the revised program SANCMTJ. Finally, the effect of eccentricity on the stress at the possible hot spots is discussed.
