航母阻拦索是舰载机着舰时与阻拦装置接触的关键部件，是舰载机的“生命线”，目前国内外航母多采用液压式阻拦装置，使用的是钢制阻拦索。为了满足舰载机重量范围更大的要求，人们将目光投向合成纤维制阻拦索，希望能成为新型阻拦索。对钢制阻拦索及合成纤维制阻拦索的结构特点及检测方法进行分析，针对舰载机着舰的对中及偏心情况，基于波动传载理论建立数学模型，对钢制阻拦索的应变载荷及合成纤维制阻拦索的拉伸力进行对比计算分析。研究结果表明：钢制阻拦索具有良好的抗拉强度及抗冲击能力，而合成纤维制阻拦索具有良好的强度重量比及柔性，较强的抗弯曲及抗冲击能力，在阻拦过程中受偏心程度的影响较小。
As the life line of the carrier-based aircraft, arresting cable directly contacts with the arresting system when hooking. In order to enlarge the capacity tonnage of carrier-based aircrafts, synthetic material arresting gear cable is considered to be a new direction of this field. This study analyzed the structure and test methods of these two kinds of cables, and calculated the strain basing on mathematical model according to the situation of centerline engagement and off-center engagement. The results show that:the steel cable has good tensile strength and impact resistance, while synthetic cable offer great performance in terms of the strength-to-weight, flexibility, bending resistance, impact resistance, and off-center engagement effect.
