砰击压力 meaning in English
slamming pressure
Examples
- How to compute the slamming press of ship bow in waves is a complex problem which is not settled completely till now . it involves the dynamic features among air , fluid and structure
如何计算在波浪中运动的船舶底部的砰击压力，这是个相当复杂的问题，至今尚未能很好地解决，它涉及到空气-流体-结构三者之间的动力特征。 - 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。 - Based on the above work , the calculation formulae of nominal slamming pressure and the bearing capability of the bottom plates in the rules are modified , and the safety coefficients are evaluated referring to the target reliability specification , then the more reasonable formula of assessing the slamming strength of bottom of the bow is given
在上述工作的基础上，对我国建造规范中原有的砰击压力名义值和底板承载能力名义值的计算公式进行了修正，并参照选定的目标可靠性指标求出了安全系数，给出了更为科学合理的船首底部砰击强度定值评定公式。 - At this instant , bottom plates experience large slamming pressure , which can damage bottom plates . the major content of this thesis is to calculate slamming pressures and ultimate bearing capacities more rationally by probabilistic analysis method , and to estimate the safety by reliability analysis method
本文的主要内容就是在考虑各种不确定性因素影响的情况下，用概率分析的方法较为合理地计算作用在底板上的砰击压力和底板极限承载能力，并用可靠性方法合理评定底板的安全性。
