The Non-linear Analysis of the Contact Problem Between the Hovercraft Cushion and the Vehicle Decks

The non-linear contact problem exists between the hovercraft cushion and the landing craft＇s vehicle deck. The maximum values of the stress and displacement causing from the 4 different contact loadcases are analysed. Via comparing with the results of the calculation of the linear model, the most dangerous loadcase is obfained. The results are confirmed by another example of the similar case.
