Structural Optimization Design of Anti-Collision Sealing Cylindrical Rubber Cushion

Abstract

At present, it is inconvenient for use due to huge volume of common inflatable rubber fender. This paper introduces a design of cylindrical rubber sealing cushion which can be applied to various occasions to protect ships, dock and pier facilities. The key of air cushion technique is that it can produce a large displacement to buffer deformation and to reduce the exchange of energy. It plays a role to increase the time of collision, and then reduces the force of collision. Meanwhile, it also has good ability to adapt the tilted contact and it can float on the water surface, etc. This paper makes a feasibility analysis and strength calculation by doing theoretical calculation, and then making a force-test simulation by using ANSYS software, and do some structure optimal design according to the results of finite element analysis.
