Nagata, A., Ushijima, S., Mukai, S., and Hayashi, E., "Explication of Gasket for Sealing of Super Rough Surface," SAE Technical Paper 2012-01-0958, 2012, doi:10.4271/2012-01-0958.
The research study experimented and analyzed the relation between a super rough surface and the seal of the gasket. It groped for the relation of the seal by the seal testing and FEM by using several different type of jig and gaskets. As for the seal of the gasket, the thing that greatly depends on the contact range and seal side has been understood. The improvement of the seal was tried by using not only upper and lower sides but also sides that were the concepts of a general seal as a sealing surface.
