slamming pressure 中文意思是什麼
slamming pressure
解釋
砰擊壓力-
For this reason, the following problems are researched emphatically : firstly, the long - term prediction method for calculating the extreme values of slamming pressure is founded. the effects of sea conditions, ship speeds, traveling directions, loading conditions on the results of long - term prediction are studied. on this basis, the computing process is simplified rationally, so as to this method can be used in practical engineering computations
為此，本文主要在下面幾個方面進行了探索：首先，建立了底板砰擊極值壓力的長期預報方法，通過分析海況、航速、航向角、裝載狀態等不同的影響，合理簡化了長期預報的計算過程。 -
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
在上述工作的基礎上，對我國建造規范中原有的砰擊壓力名義值和底板承載能力名義值的計算公式進行了修正，並參照選定的目標可靠性指標求出了安全系數，給出了更為科學合理的船首底部砰擊強度定值評定公式。 -
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
本文的主要內容就是在考慮各種不確定性因素影響的情況下，用概率分析的方法較為合理地計算作用在底板上的砰擊壓力和底板極限承載能力，並用可靠性方法合理評定底板的安全性。 -
Under confused sea condition, the structures may subject to very strong w ave impulsive 1oad due to slamming by the wave with significant crest when waves propagate underneath the structure and surge up to its subface. previous studies indicate that impact pressures are characterized by an initial peak pressure of considerable magnitude but of short duration occurs, followed by a slowly - varying uplift pressure of less magnitude but of considerable duration, and which typically is first positive, then decreases to zero and becomes negative, in hostile sea state, the peak pressures may cause the damage of the horizontal members of the structures or make the whole superstructure collapsed
若這些海上建築物的上部結構底高程較低，在惡劣海況下當大波浪在其面板下面通過並與之接觸時，面板下面除了作用有強度變化較緩慢的波壓力外，在波峰剛接觸到面板時尚存在著歷時很短但強度極大的沖擊壓力，這種極強沖擊荷載會引起建築物的整個上部結構失穩或造成局部破壞。 -
The numerical computation results of wave pressure on open - piled wharf deck for different parametric cases are verified by the experimental results. great progress is made on the numerical model for the study of wave slamming problem
文中對不同情形的波浪沖擊問題進行了數值計算，並用物理模型試驗結果對數值模型進行了驗證，在建立波浪沖擊問題的數值模型方面取得了重要的進展。
