基于先导发展模型的船舶直击雷防护分析方法
Analysis method for direct lightning protection of ships based on the leader progression model
摘要
Abstract
The height of precision instruments and detection devices is higher than other equipment on large ships,and they have protruding tips and poor antiinterference performance.Thus,lightning protection for modern ships has become an important research topic.This study proposes the lightning protection analysis method for ships based on a probability function developed using the improved Wiesmann-Zeller model,considering complex marine environments.The proposed method establishes the sea surface lightning pilot development model.Taking a large ocean-going survey ship as the object,the proposed method is used to analyze the probability distribution of light-ning strike attachment points and multiple lightning rods based on the characteristics of the ship.Based on the pro-posed model,the process of lightning strikes against ships was simulated by Matlab.The relationships between pro-tection range,effectiveness,position,quantity,and height of lightning rods were revealed.The lightning strike probability and protection effects under different numbers and heights of lightning rods were compared and ana-lyzed,verifying that the three-needle unequal height is the best solution,which can guide and improve actual engi-neering practice and ensure that ships are protected from lightning.关键词
