| The possibility of ship-bridge collision is on the rise with a large number of the acrosssea bridges being built and the increasing speed of ships. The losses of lives and property arestriking,as well as the destruction to the environment. In order to avoid or reduce thecatastrophic losses in the accidents it is important to study the mechanism of ship-bridgecollision, especially the anti-collision device. It is of very importance of theoretical andrealistic significance.Based on the above summary of previous research Funabashi collision, the impact on thewhole process of ship and bridge collision device simulation modeling, and simulation of theprocess of the problems encountered are described, specific work and research results are asfollows:(1):Funabashi existing domestic and collision theory to summarize, the formula for shipcollision force countries to make the necessary calculations described, and the characteristicsof the various piers anti-collision devices for analysis.(2):In view of the large number of domestic and foreign literature on the basis of thispaper to be applied to the simulation software Midas FEA and ANSYS/LS-DYNA finiteelement software necessary exposition, and for the modeling process encountered issues suchas the definition of contact with friction, hourglass control, meshing, time-step control, etc.are described, and the parameter values give a clear definition.(3):Relying Yiling Yangtze River Bridge main pier protection device engineeringbackground, the use of anti-collision devices Midas FEA software for static analysis usingANSYS/LS-DYNA software Funabashi collided dynamic analysis, a comprehensive staticanalysis and dynamic analysis the results of the reliability Yiling Yangtze River Bridge mainpier to evaluate anti-collision devices, which provide the basis for future optimization design. |
