为探究波浪对非对称式半潜起重平台不同位置的砰击载荷特性及其分布趋势，在不规则波条件下进行多种入射角下的波浪砰击载荷数值模拟，重点分析船体上甲板各区域以及船体立柱各区域。结果表明，决定砰击峰值压强大小的因素是迎浪侧立柱跨度，跨度与峰值压强呈正相关规律。
In order to explore the slamming load characteristics and its distribution trend of asymmetric semi-submersible lifting platform at different positions, this study carried out numerical simulation of wave slamming load at various incident angles under irregular wave conditions, focusing on the analysis of each area of the upper deck of the hull and each area of the hull column. The results show that the factor that determines the peak pressure of slamming is the span of the upright post on the side facing the waves, and the span is positively correlated with the peak pressure.
