非金属垫片分形泄漏模型理论分析

摘要

以分形几何为基础,建立非金属质垫片分形泄漏模型.研究表明,载荷稳定时垫片中压力分布呈幂律变化,垫片泄漏率与压差成正比,且与分形垫片参数、异常扩散系数等有关.%Based on fractal geometry, a fractal leakage model for nonmetallic gasket was established. The results indicate that the pressure on gaskets varies in power law at a steady load, and its leakage rate varies with differential pressure and relates to gasket specifications and anomalous diffusion coefficient, etc.
