4440x4010x200防冲板强度计算书.doc1. Calculation Conditions ( 计算条件)Contact angle(接触角度): 10o Fender type(护舷类型) Frame Size(防冲板尺寸宽 x 长 x 厚) :4010Bx 4440L x 200H 2. Calculation of Sectional Force (局部力的计算方式)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,就在船只接触护板同时弯曲矩 M 变成最大 (M最大)。因此在M最大 下的M最大 和 S最大 (最大局部力)应按以下方式计算2.1 Maximum Bend Moment ( M max)最大弯曲矩 (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. (假设船只以10度角接触护板,而护板可认作是一个横梁, 橡胶部分认作是弹簧,链条部分的位置作为支点,则弯曲矩可如下计算)
