1. Calculation Conditions ( 計算條件)
Contact angle(接觸角度): 10o
Fender type(護舷類型)
Frame Size(防沖板尺寸 寬 x 長 x 厚) : 4010B x 4440L x 200H
2. Calculation of Sectional Force (局部力的計算方式)
Among sectional forces, Bend Moment M becomes maximum just before a vessel contact to the board (M max). Thus M max and S max ( maximum sectional force) under M max could be calculated shown below
(在局部力之中,就在船只接觸護板同時彎曲矩 M 變成最大 (M最大)。因此在M最大 下的M最大 和 S最大 (最大局部力)應(yīng)按以下方式計算
2.1 Maximum Bend Moment ( M max) 最大彎曲矩 (M最大)
Provided a vessel contacts a board at angle of 10 degrees horizontally, the board is considered to be a beam regarding a rubber parts as a spring and a chain attachment position as a fulcrum. Thus, bend moment could be calculated. (假設(shè)船只以10度角接觸護板,而護板可認作是一個橫梁, 橡膠部分認作是彈簧,鏈條部分的位置作為支點,則彎曲矩可如下計算)
