1 利用積分可得到船縱向承受的剪力從和彎矩。由于累積誤差的存在,很難保證駁船承受的浮力和重力完全平衡,即駁船首尾端點(diǎn)處剪力和彎矩一般不為零。為此,需要對剪力和彎矩曲線進(jìn)行不封閉修正。通常是將端點(diǎn)不為零的剪力彎矩按線性比例關(guān)系分配到曲線上 2 剪力和彎矩曲線積分分別從首尾兩端開始進(jìn)行并積分至船中。這樣,船中處存在兩個不同的剪力和彎矩值,將二者求取平均值作為該處的剪力和彎矩結(jié)果。 |

Due to the existence of accumulative error, it is difficult to guarantee that bearing buoyancy and gravity of barge can be balanced completely. That is to say, shear force and bending moment at fore-aft endpoint of barge is not normally zero. Therefore, its shear force and bending moment curve should be treated with non-seal correction, which makes the shear bending moment whose endpoint is not zero be assigned to curve according to linear proportional relationship. 2 剪力和彎矩曲線積分分別從首尾兩端開始進(jìn)行并積分至船中。這樣,船中處存在兩個不同的剪力和彎矩值,將二者求取平均值作為該處的剪力和彎矩結(jié)果。(第一句是不是有點(diǎn)問題,,看不懂)。。 2.Then, there exist two different shear forces and bending moment values in barge, and their average value can be the result of shear force and bending moment at this place, |
