现代火炮身管要求承受高膛压、高初速、远射程和减轻重量等战术技术性能,随之而来炮管烧蚀磨损和疲劳问题十分突出。炮管烧蚀磨损已经过几十年的广泛研究,取得了一些突破。近十多年来对炮管疲劳的研究格外受到重视,在防止炮管使用中发生疲劳破坏方面也取 Modern artillery barrel requirements to withstand high-pressure, high-speed, long range and reduce weight and other tactical and technical performance, followed by ablation tube wear and fatigue problems are very prominent. Barrel ablation wear has been extensively studied for decades and some breakthroughs have been made. In the recent ten years, the research of barrel fatigue has been paid more attention, and it also takes the aspect of preventing fatigue damage during the use of barrel
