摘　　要：气垫船着陆垫与车辆甲板之间构成非线性接触问题,通过有限元方法,计算并分析不同工况下由接触导致的甲板各构件的最大应力和最大位移值,并与采用均布载荷直接加载在甲板上的线弹性计算结果比较,得出最危险工况,并通过一简单算例分析了结果的合理性。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.
