With the development of my country's shipping industry, there are more and more demands for wharf and marine fenders, and the requirements for fender performance are also getting higher and higher. Among them, rubber fenders are the most widely used due to their good toughness and impact resistance. At present, there are many manufacturers of rubber fenders in my country, and the products are mixed. In order to survive in the fierce market competition, some manufacturers unilaterally use low-price competition as the main means, do not strictly abide by relevant standards and processes, use low-quality raw materials, or use excessive recycling Glue is used to reduce costs, which brings great hidden dangers to the safety of docks and ship berthing. Relevant experts said that rubber fender manufacturers should strictly implement relevant national standards, and strict technological processes, enhance independent innovation capabilities, continuously improve product quality, and provide reliable and safe products for my country's shipping industry and shipbuilding industry.
It is understood that there are many types of rubber fenders currently on the market, mainly buckling type, inflatable type, laterally loaded cylindrical type (drum type), butt V type (ie X type), and flexible pile type. When designing and producing rubber fenders, manufacturers should consider the reaction force acting on the hull and docking components, the deformation of the fender after absorbing the kinetic energy of the ship, the reaction force acting on the hull caused by fender deformation, the relative stiffness of the fender, The effectiveness of fender energy absorption in non-frontal berthing, the rate at which fenders decelerate the ship's berthing speed, the coefficient of friction between the fender system and the hull, the capital investment and maintenance costs of the fender system and supporting components, the hull There are many factors such as the contact mode with the fender. Users can choose different types of rubber fenders according to the actual situation. Except for tugboats and small ships, large-tonnage ships are generally not equipped with rubber fenders. When berthing, they mainly use inflatable rubber fenders to protect the wharf and hull.
