    摘要:

    为研究螺栓法兰接头用碟形弹簧压缩回弹性能,建立碟形弹簧力学性能分析的弹塑性有限元模型,并通过试验验证其可靠性。应用ABAQUS软件对碟形弹簧压缩回弹过程进行分析,讨论碟簧外内径比、倾角和厚度对碟簧压缩回弹性能的影响。结果表明:碟簧的压平载荷随厚度、倾角的增加呈上升趋势,随外内径比的增加呈下降趋势;回弹率随厚度、倾角、外内径比的增加均呈下降趋势。基于正交试验分析方法,结合量纲分析,建立螺栓法兰接头用碟形弹簧压平载荷和回弹曲线的预测模型,并验证其可靠性。

    Abstract:

    In order to study the compression resilience of disc spring for bolted flange joint,the elasticplastic finite element model for mechanical performance analysis of disc spring was established,and its reliability was verified by experiments.ABAQUS software was used to analyze the compression resilience process,and the effects of the ratio of outer diameter to inner diameter,inclination angle and thickness of disc spring on the compression resilience of the disc spring were discussed.The results show that the flattening load of the disc spring is increased with the increase of the thickness and inclination angle of disc spring,and decreased with the increase of the ratio of outer diameter to inner diameter of disc spring.The resilience is decreased with the increase of the thickness,inclination angle and the ratio of outer diameter to inner diameter of disc spring.Based on the orthogonal experimental analysis method and the dimensional analysis,the prediction model of flattening load and rebound curve of disc spring for bolted flange joint was established,and its reliability was verified.
