Abstract

PURPOSE: To conform to a requested energy absorbing performance and a scale of a wharf installation most properly by a method wherein a configuration of a hollow cylindrical body of rubber is constituted so as to satisfy specified formulas.
CONSTITUTION: Formulas (1), (2) are introduced under an assumption that a reactional force generated when a hollow cylindrical fender is compressed by aproach of a ship is caused by a bending deformation only. In the formulas (1), (2), an amount of absorbed energy per unit length when the hollow cylindrical fender 1 having an outer diameter D and an inner diameter A is compressed by an amount of displacement U is indicated by W, an amount of absorbed energy per unit volume under the same condition is indicated by Wo and A/D is expressed by m. In case these formlas are utilized, the maximum amount of absorbed energy may be obtained by determining a ratio of the outer diameter to the inner diameter into a predetermined value in spite of the size of the outer or inner diameter and the amount of absorbed energy per unit volume of rubber may also be maximized.
