针对海上漂浮软管波浪载荷计算，分析了软管在海上的形态和受力特点，建立了海上漂浮软管力学分析模型，指出直接运用现有Morison方程计算漂浮软管波浪载荷存在的不足，并根据基本原理提出了改进Morison方程。对海上软质管线处于一定海况，分别运用改进Morison方程与现有Morison方程计算海上波浪载荷，并运用ANSYS软件建立软管模型，结果表明现有Morison方程不适用于计算海上漂浮软管波浪载荷，载荷计算结果偏高约15%，从而验证了改进Morison方程的精确性，有利于准确分析波浪载荷对海上漂浮软管的作用情况。%For wave load computation of floating hose, this paper analyzes the morphology and mechanical characteristics of offshore hose by establishing the mechanics analysis model, and points out the deficiency of the use of the existing Morison equation to calculate the wave load of floating hose. Therefore, the improved Morison equation is put forward based on its basic principle. For offshore hose in certain sea conditions, the improved Morison equation and the existing one are respectively used to calculate the wave load, and the hose model is established with the ANSYS software. Results show that the improved Morison equation optimize the accuracy of the floating hose wave load computation, which is more suitable for the analysis of the effects of wave load.
