摘要
由薄壳的弯曲理论，推导出了填料密封侧压系数与测力环周向应变间的函数关系。以环状柔性石墨成型填料为试验样品，确定了多圈密封填料侧压系数沿轴向的分布。
According to the bending moment theory of membrane shell,the functional relations are obtained between lateral pressure coefficients of the packing and circumferential strain of thinwalled sleeves.Taking expanding graphite packings as speimens,the distribution of lateral pressure coefficients are determined by means of experiment.
