初挠度 meaning in English
initial deflection
Examples
- In the hogging condition , double bottom and the side shell remain the ultimate bucking strength , deck and upperwing tank remain the yield stress , and the other parts keep elasticity . then the key to calculate the ultimate strength of ship hull girders is to ascertain the ultimate bucking strength of the stiffened panels . in this regard , the developed formulation is designed to be more sophisticated than previous simplified theoretical method for calculating the ultimate strength of stiffened panels under combined in - plane bending and lateral pressure . fabricatio n - related initial imperfections ( initial deflections and residual stresses ) are included in the panel ultimate strength calculation as parameters of influence . all possible collapse modes involed in collapse of stiffened panels , including overall buckling collapse , column or beam - column type collapse , tripping of stiffeners and local bukling of stiffened web are considered
确定了船体梁整体破坏时的剖面应力分布之后，关键在于确定板架的极限屈曲强度。本文充分考虑了在纵向弯曲、横向压力作用下加筋板可能发生的几种破坏模式，即板架的整体屈曲破坏、梁柱形式的破坏、筋的侧倾、腹板的屈曲并同时考虑了初始焊接残余应力、初挠度的影响，使其更精确的计算加筋板的屈曲强度。对于加筋板中加强筋腹板的局部屈曲，采用解析法推导出筋的腹板的挠度方程及其边界条件，求解相应的方程，从而计算出腹板的局部屈曲应力。
