本文根据我国及法国船舶建造规范的规定,以静水弯矩作为决定船体纵强度是否满足要求的主要衡准,介绍及探讨船舶积载计算中简便、实用的纵强度校核方法。作者推荐使用一种以公式计算方法为基础所绘制的,船舶驾驶人员希望采用的强度曲线图,作为校核船舶纵强度的更加方便、快速的方法。在远洋船舶上,使用一种带程序计算的小型电子计算器,可以作为上述二种方法的补充。有关船舶设计制造部门应提供有关纵强度校核的计算资料及图表给船舶驾驶人员使用,以便在船舶积载中推广实用的纵强度校核方法。
In this paper, according to the regulations of China and French shipbuilding codes, the method of hydrostatic bending moment as the main criterion to determine whether the hull longitudinal strength meets the requirements is introduced and discussed. The authors recommend the use of a strength graph based on a formula calculation method that ship drivers would like to use as a more convenient and rapid method of checking the ship’s longitudinal strength. On an ocean going ship, a small electronic calculator with a program calculation can supplement the above two methods. The relevant ship design and manufacturing department shall provide calculation data and charts relating to the longitudinal strength check for use by ship drivers in order to promote practical methods of longitudinal strength checking in ship stowage.
