Abstract : This report details the development of a long life submarine seal. In the first portion of the report, three different long life designs based on the waviness concept are described. Design details and test results are given. The conclusions reached are that the first design gives long life but is too complicated. The second design is much simpler but still gives long life. The third design is very simple but life may be compromised. Even so, the fixed wave (third design) appears to be the best way to apply the waviness principle. A new type of grinding apparatus was designed to produce the wave. Details of seal ring deflection calculations are given. A ring finite element analysis and ring deflection program are given. A contact model is presented. Deflection studies on actual submarine seal rings are presented, and it is shown how present designs are sensitive to lock ring groove waviness. Experimental verification is provided for the contact model. Work on a nonlinear joint model is described. Experiments to validate the existence of microasperity lubrication in water are described and dismissed. A unique apparatus was constructed. Experiments suggest surface roughness on a microstructure level does not cause a large hydrodynamic load support in water. Several seal analysis programs are described. One of the programs provides for a fully automated heat transfer analysis of seal pairs.
