| 摘要： | This research project evaluated the structural and performance characteristics of two cylindrical rubber fenders under simulated marine vessel loading. The purpose of this research effort is to establish design and performance criteria for vertically floating rubber fenders that can be applied to the specific needs of the Alaska Marine Highway System (AMHS) ferry vessels. Two foam filled, rubber skinned, cylindrical fenders were fabricated and load tested. The test fenders were 6-feet in diameter by 6-feet long comprised of a 30-inch diameter by 1/2-inch wall steel pipe sleeve wrapped with closed cell polyethylene foam and encapsulated with a 1.25-inch thick skin of rubber reinforced with fiberglass filaments. One test fender contained a foam density of 4 pcf. The other test fender had a foam density of 6 pcf. Fender testing consisted of the application of a load to the fender body intended to simulate the shape and size of the AMHS vessel sponson that would be in contact with the fender under actual conditions. Load and deflection tests were performed utilizing a calibrated hydraulic press and deflection sensors. Load testing was performed at three locations, 90 degrees apart within the center of fender body. Continuous load, deflection and time data resulting from fender deformation under load was recorded. Cyclic load testing was also conducted on the fender body to determine if multiple load applications would cause material damage. The load and deflection data was plotted and analyzed to determine load versus deflection curves and the available kinetic energy or load absorption capacity of each test fender. Load versus deflection and a kinetic energy versus deflection curves for each of the fenders are provided in the report. The report further summarizes loading conditions and applicable energy requirements applicable to the use of this type of fender under AMHS service conditions. |
