Examples
- Since kamen and vagena , many researchers have discussed it in theory and experiment method . the main content in this paper is to set forth the slamming press calculations in dnv rules , gl rules and lr rules and the requirements for slamming strengthened bow structure and some comparisons ; slamming strengthened bow structure design for a bulk is carried out using dnv rules , and comparisons among several design schemes is carried through when heavy loading draft status replaces light loading draft status in practice . the results from above have been applied in ship production ; it is significant for ship structure improvement latter to calculate slamming press with direct calculation method , and then to design bow structure with dnv rules
本文的主要内容是分别阐述dnv 、 gl 、 lr三种规范对底部砰击压力计算及底部砰击加强结构设计的一般要求并进行一些分析比较：用dnv规范对某型船( 27000t散货船)进行具体的底部砰击加强结构设计，并就实际生产中产生的重载吃水状态改轻载吃水状态而出现的几种设计方案进行比较，其具体结果现已用于实际生产；用直接计算法确定砰击压力，再用dnv规范进行底部结构设计，对于后续船的改进均有指导意义。 - In order to resolve the strength problem of 74500dwt bulk carrier on launching way , two aspects of problem are investigated in this report : 1 ) the analysis and calculation of the force act on the hull and the launching way when ship launching ; 2 ) the strength analysis and calculation of bottom structure in forward area during ship launching
为了解决74500吨散货船下水时船体结构的强度问题，本文主要对两方面的内容进行了研究： 1 )船舶纵向下水时的受力分析和滑道反力计算： 2 )艉浮时艏部区域底部结构强度分析计算。 - Double - tower structure ( dts ) is a new type super high - rise building structure system , which is a complicated new type high building structure combined by the base structure , it is more widely used in the practical engineering , owing to the diversification in the structure and space assembling . although doing some research on the structure , the research on the performance under the static loads is not deep , specially the research on the dynamical characteristic
双塔结构是一种新型的超高层建筑结构体系，是通过底部结构将现有的结构形式经过组合而形成的一种复杂的新型高层建筑结构形式，由于它在结构与空间布置上的灵活性在实际工程中有越来越多的应用，虽然对这类结构的研究已经进行了一些，但对它的受力性能的研究特别是它的动力性能的研究还不够深入。
