Study on Probability Distribution of Ship-Bridge Collision Force Formula

Abstract

The probability distribution with different ship-bridge collision formulas are studied using Monte-Carlo method. It used the distribution fitting tool with the sampling results, and got the forms and parameter of probability distribution of different ship-bridge collision force formulas. The results indicate that the logarithmic normal distribution and generalized extreme value distribution can well reflect the probability distribution characteristics of ship-bridge collision formula. The probability distribution characteristics proposed can be directly used in the reliability index calculation of bridge under the ship collision.
