Fractal characterization of seal surface topography of metallic gaskets;

金属垫片密封表面形貌的分形表征

The sealing mechanism,leakage characteristic and microcosmic sealing process of metallic gasket were investigated.

对金属垫片的泄漏形式和微观密封过程进行分析研究,并对金属垫片密封性能进行试验研究。

According to the fractal geometry theory and the non-compressed viscous fluid laminar flow theory,the leakage model of metallic gasket based on fractal parameter was established.

依据分形几何理论,结合不可压缩粘性流体层流流动理论,建立基于分形参数的金属垫片泄漏模型,该模型揭示了泄漏率与密封表面形貌之间的关系。
