波浪载荷和惯性载荷是自升式平台设计的核心基础,由于波浪参数与波浪载荷及惯性载荷之间的关系较为复杂,波浪载荷和惯性载荷的确定一直是自升式平台设计和计算中的重点和难点。本计算分析基于Morison方程,以某四桩腿自升式平台为例,利用水动力软件,分析波浪周期和波高对于波浪载荷的影响,探讨了最大波浪载荷和波浪总载荷(波浪载荷+惯性载荷)的确定方法,给出平台波浪载荷和波浪总载荷的包络值,为后续自升式平台的研发提供参考。
Wave-induced loads and inertial loads are the critical basis of self-elevated platform design. The relationship between wave parameters and wave-induced loads and inertial loads are complicated. The determination of wave-induced loads and inertial loads are always one of the key points and difficulties for the self-elevated platform design and calculation. Based on Morison equation, taking a self-elevated platform for example, this study uses hydrodynamic software to analyze the influence of wave period and wave height upon wave-induced loads, and discuss the way to determine maximum wave-induced loads and wave-induced total loads (wave-induced loads+inertial loads).The envelope curve of wave-induced loads and wave-induced total loads is proposed., which provides reference for the self-development and innovation of subsequent self-elevated platform.
