柔性石墨金属波齿复合垫片金属骨架结构参数的研究

Study on Metal Skeleton Structural Parameters of Flexible Graphite Corrugated Metal Gaskets

在金属波齿复合垫片的金属骨架上,施加一定的压紧应力(45 MPa)。在三组的不同结构参数下,采用有限元法对三种不同齿尖厚度做对比分析,了解它的密封性能。分析结果表明,在齿尖部位,随着其厚度的增加,波齿环上的应力出现迅速均化的现象,整体变形减小。可知,适当的齿尖厚度,能够使波齿垫片的承载能力得到极大的提高。

Exerting a certain degree of compression stress （45 MPa） on metal skeleton of the composite corrugated metal gasket, under three groups of different structural parameters,three different tooth tip thicknesses were compared and analyzed by the finite element method to understand the sealing performance. The analysis results show that at the tooth tip site, with the increase of its thickness, the stress on the wave gear ring appears the phenomenon of rapid homogenization, the overall deformation decreases. The results show that suitable tooth tip thickness can increase the carrying capacity of the corrugated gasket.
