摘要:
研究了疲劳载荷下柔性石墨金属波齿复合垫的力学性能和蠕变性能. 对垫片进行了373 K和573 K两种温度下的循环加载实验,基于得到的应力-变形量实测数据,通过计算压缩模量和卸载模量分析了其压缩回弹特性;考虑温度和金属骨架厚度的变化,探索了蠕变-疲劳的交互作用对垫片的影响. 研究表明:疲劳载荷下随着时间增长垫片压缩速率增加,回弹速率减小;在稳态蠕变阶段,蠕变-疲劳载荷的交互作用使垫片的蠕变曲线出现周期性波动,波动周期不随实验条件改变而改变.
Abstract:
The mechanical and creep properties of flexible graphite corrugated metal gaskets were studied. The cyclic loading tests of gaskets at temperatures of 373 K and 573 K were conducted. Based on the measured stress?strain data and the calculation of compression modulus and unloading modulus,the compression resilience characteristics of the gaskets were analyzed. Considered the influence of the temperature and the thickness, the effects of interaction between creep and fatigue on the gaskets were explored. The result shows that the compression rate of the gaskets increases and the resilience rate of the gaskets decreases with the increasing of time under fatigue load; in the steady creep stage, the creep curve of the gasket appears cyclical fluctuations under the interaction between creep and fatigue, which has no relation with the experiment conditions.
