摘要
Precise impact definite element analysis model for 3 000~50 000 t dead weight ton at 5 typical ships in total is established,and LS-DYNA impact analysis software is used to calculate and obtain corresponding ship impact time course.Definitions for 3 equivalent static forces of ship impacts:Maximum peak value,local mean,and global mean are given to study relations between the 3 equivalent static forces of ship impacts and ship load weight ton and impact speed.Based on statistic analysis and parameters simulations on the result of impact calculation,statistic relations for calculating bridge equivalent static force of ship impact are put forward,and are compared and discussed with the calculation formula for equivalent static force of ship impact listed in American AASHTO Guide on Bridge Ship Impact Design,European Uniform Code 2.7 Volume,and domestic Basic Criteria for Railroad Bridge and Culvert Design(TB10002.1-99).
