摘要
通过对盖板与壳体在不同联结构造下,节点试验的比较,合理选择了构造形式,采用L9(3~4)正交表,安排原型节点的破坏性试验。极差分析表明,壳体壁厚是影响节点承载能力的最显著的因素,经回归分析,得出计算极限承载能力的经验公式,根据实测应变,计算应力强度,并描述其表面分布。
Based on the tests of joints with different construction,a kind of rational construction was elected.Destructive tests of prototype joints were arranged by the method of optimal design.By analysis,it was indicated that shell thickness is the most remarkable factor effecting bearing caparity.Empivical formula calculating limit bearing capacity was produced. Form the strain measured,regular pattern of stress strength calculated was described.
