    Modelling Strategy and Parametric Study of Metal Gaskets for Automotive Applications

    Fabio Bruzzone, Cristiana Delprete, Carlo Rosso*

    CMES-Computer Modeling in Engineering & Sciences, Vol.125, No.1, pp. 51-64, 2020, DOI:10.32604/cmes.2020.011023

    Abstract This paper is focused on finite element simulation of cylinder head gaskets. Finite element codes support several methodologies, each of which has its own strengths and weaknesses. One of the key points lies in the influence of the gasket geometry on its final behaviour. Such a contribution can come from the detailed modelling of the gasket or by defining a global non-linear behaviour in which material and geometry non-linearities are summarised. Two approaches were used to simulate the gasket behaviour. The first one consists in using a 2D approach, which allows to model through-thickness non-linear behaviour of gasket. The second… More >

    Robust Design Methodology for Sealing Performance of Gaskets

    Hasan Aftab Saeed1, Satoshi Izumi1, Shinsuke Sakai1, Shigeyuki Haruyama2, Masato Nagawa3, Hideki Noda3

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.5, No.1, pp. 21-26, 2008, DOI:10.3970/icces.2008.005.021

    Abstract This is the first attempt toward the development of robust design methodology applicable to gaskets as there is no such precedent in the sealing industry. This was achieved by drastically transforming the traditional approach toward the solution to leaking problem. This paper deals with a new all-metal gasket that incorporates strategically located circumferential annular lips that form seal lines with the flanges. The gasket, due to its special shape makes use of the material's spring effect, resulting in sealing performance. This approach is clearly distinct from the traditional one based on material development. By transforming a material development problem into… More >
