Finite Element Analysis Of Yangtze River Bridge Collided By Ship

The ship-bridge collision is an accidental affairs,but the the ship-bridge collisions take place in the world-wide locations,and usually in property lose,personnel dead and injured etc.disaster result.For reducing the ship-bridge collision trouble,in recent years some countries all successively to the collision mechanism of the ship bridge and defended the constitution to carry on a great deal of research,obtain some terrific value results.The ship-bridge collision is a more complicated nonlinear dynamics problem,is ships and bridges in very short time,carry the function in the huge impact lotus under the occurrence of a complicated nonlinear motive responds to the process,the district of the collision will enter the fluxion stage,appearing material accept defeat,break etc. circumstance,appear the bridge in collide process nonlinear motive respond to.Because the factor of the influence ship-bridge collision is more,want the result to the ship-bridge collides the process to carry on the precision what analysis is not a easy realization,rather than a technical development of line but can carry on the emulation to the whole process that the ship bridge collide,but get thus already can with good satisfy the demand of the engineering fulfillment.This text combines in tallying up the research result of the foundation and the extensive investigations heavy celebrate,with the example of ZhongXian YangZhi River bridge,usage ANSYS/LS-DYNA procedure gathers to pack the ship work condition that is touching the main bridge buttresses and leading the bridge buttresses to analysis a 5000 ton,getting the ship-bridge collision of bump the shot dint,and carried on with the number that various norm calculation get more analytical.At the same time,aim at the high and change the characteristics,research on the different water level,logarithms the value imitated the true calculation to as a result carry on the analysis comparison, get under different circumstance of the regulation that bridge respond,the constitution that aims at to defend to bump the facilities put forward the homologous standpoint.
