摘要:
采用ABAQUS有限元数值模拟研究柔性石墨金属波齿复合垫片的不同金属骨架在一定齿数、齿深和齿厚时的变形特性,在齿数N=3~7、齿深H=0.3~0.7 mm、齿厚t=1~1.6 mm参数组合下的波纹形金属骨架的压缩回弹性能较好。复合垫片的压缩量主要由柔性石墨提供,而回弹量则主要取决于金属骨架的结构形式和参数。对波纹形金属骨架与柔性石墨复合后的垫片的压缩回弹性能进行了数值研究,以复合垫片最佳压缩率和最大回弹率为目标,对金属骨架的结构参数进行了优化,优化后的波纹形复合垫片的骨架结构参数为齿数N=3,齿深H=0.7 mm和齿厚t=1 mm; 柔性石墨层厚度T=1.5 mm。
Abstract:
By finite element numerical simulation ABAQUS software, the deformation performance of metallic frameworks of flexible graphite gaskets reinforced by corrugated metal sheet with different tooth number, tooth depth and tooth thickness were investigated. The corrugated shape frameworks with tooth number N=3-7, tooth depth H=0.3-0.7 mm, and the tooth thickness t=1-1.6 mm had better compression-resilience performance. The compression of composite gaskets was mostly provided by flexible graphite while its resilience was mainly dependent on the structure form and parameters of metallic frameworks. Numerical research was performed to study the compression and resilience performance of the gasket composed of corrugated metallic framework and flexible graphite. The structure parameters of metallic framework were optimized to obtain the best compressibility and maximum resilience rate. The optimized parameters were as follows:tooth number N=3, tooth depth H=0.7 mm, tooth thickness t=1 mm, and the thickness of the flexible graphite layer T=1.5 mm.
