4440x4010x200防沖板強(qiáng)度計(jì)算書(shū).doc
1. Calculation Conditions ( 計(jì)算條件) Contact angle(接觸角度): 10o Fender type(護(hù)舷類(lèi)型) Frame Size(防沖板尺寸 寬 x 長(zhǎng) x 厚) : 4010B x 4440L x 200H 2. Calculation of Sectional Force (局部力的計(jì)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(hù)板同時(shí)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(jì)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(hù)板,而護(hù)板可認(rèn)作是一個(gè)橫梁, 橡膠部分認(rèn)作是彈簧,鏈條部分的位置作為支點(diǎn),則彎曲矩可如下計(jì)算)
