船舶设计初期,为了在缺少详细图纸的情况下能够快速且准确地评估集装箱船受到的风载荷,本文采用多种经验公式及规范公式法研究了集装箱船的各种风载荷系数。将上述方法得出的结果与计算流体力学(CFD)方法得出的结果进行对比,确定针对集装箱船时不同经验公式的适用程度以及准确性。研究结果表明,藤原敏文以及日本规范公式计算的纵向风载荷与数值模拟值吻合度更高;采用经验公式评估90°横向风载荷时,建议进行20%的包络值修正;在风向角为0°~90°时,建议采用规范计算和Isherwood公式评估艏摇风载荷;在风向角为90°~180°时,建议采用藤原敏文公式进行艏摇风载荷的快速评估。
In order to evaluate the wind load of container ships quickly and accurately in the early stage of ship design without detailed drawings, this paper uses a variety of empirical formulas and normative formulas to study the various wind load coefficients of container ships. The results obtained by the above method are compared with the results obtained by the computational fluid dynamics (CFD) method, and the applicability and accuracy of different empirical formulas for container ships are determined. The results show that the longitudinal wind load calculated by Fujiwara Minbun and the Japanese standard formula is more consistent with the numerical simulation value. When the empirical formula is used to evaluate the 90-degree lateral wind load, it is recommended to correct the envelope value by 20%. When the wind direction angle is between 0° and 90°, it is recommended to use the standard calculation and Isherwood formula to evaluate the yaw wind load. When the wind direction angle is in the range of 90°to 180°, it is recommended to use Fujiwara 's formula to quickly evaluate the yaw wind load.
