摘要在这篇论文中我们主要是利用Maxsurf软件及其配套的软件Hydromax来进行稳性和强度的计算。
首先,我们先使用Maxsurf来将我们的起重船船模建设出来,我们需要根据型值表数据来输入mark点。在船模建好之后,我们将船模直接倒入配套Hydromax中,在Hydromax中我们可以提取许多有用的数据,然后我们可以由此再得到初稳性高,平均吃水,自摇周期,重心到基线垂向距离,风压倾斜力臂,动稳性力臂,最大静稳性力臂,稳性衡准数,进水角等。船舶总纵强度里的一些数据例如各个站位中距尾柱的距离,重量分布,静水剪力,静水弯矩等这些数据都可以在Hydromax中十分方便的查得。最后,为了校核总纵强度,我们还需要计算出剖面模数。剖面模数的计算我们需要根据典型横剖面图来进行,我们需要计算出基线距中和轴的距离,对中和轴的惯心距,船底板剖面模数,强力甲板剖面系数,舱口模板剖面模数。这些都计算完之后,我们将计算所得值与其进行比较,从而校核完成。86316

Abstract In this paper, we mainly use the Maxsurf software and its supporting software Hydromax to calculate the stability and strength。
First of all, we use Maxsurf to build the model of our lifting ship, we need to enter the mark point according to the type of value table data。 Ship model is built in, we will ship model directly into the supporting Hydromax, in Hydromax we can extract a lot of useful data, then we can then get metacentric height, mean draft, rolling cycle, center of gravity to baseline vertical to the distance, wind pressure inclining arm, arm of stability, the maximum static stability arm, stability criterion number, inlet angle。 Overall longitudinal strength of hull in some of the data such as various stations from the column end distance, weight distribution, hydrostatic shear, hydrostatic bending moment of these data can be in Hydromax very convenient check。 Finally, in order to check the total longitudinal strength, we also need to calculate the section modulus。 Section modulus calculation we need according to the typical cross section, we need to calculate the baseline distance from the neutral axis, of the neutral axis of inertia distance, ship bottom section modulus, strength deck section coefficient hatches template section modulus。 After these are calculated, we will calculate the value of its comparison, and thus check the completion。
