摘    要:本文采用八结节点等参数环形轴对称有限单元,对静载作用下封板连接进行了弹塑性分析。探讨了封板连接的破坏模式、应力分布、位移、塑性区发展情况以及封板厚度对封板连接承载能力的影响。绘制了承载能力与封板厚度关系曲线,在有限元分析的基础上,提出了设计封板连接的计算公式及建议。

关 键 词:弹塑性分析,密封,板,联结/承载力

Abstract:In this paper,8-node serendipity quadratic element is used to make elasto-plastic analyaisof sealing plate joinders subjected to dead load.The failure mode,distribution,displacement,de-velopment of plastic zone,and effect of thickness of sealing plate on load-capacity of sealing plate join-ders are studied.The relationship curve between load-bearing capacity and thickness of sealing plate isattained.Based on the analysis by the Finite Element method,some formulas and suggestions on design-ing sealing plates are put forward.
Keywords:elastic-plastic analysis  sealing  plate  jointings/ 1oad-bearing capacity
