优化，探究了两种参数对复合材料层合板力学性能的影响规律，优选了最合理的参数设计。研究表
明：随着物体冲击速度的增加，受冲击表面达到最大凹陷深度的时间逐渐变短，同时达到的最大凹

深度逐步减小；不同防护装置的防护效果与侧边倾斜角度相关，可通过改变侧边倾角来提升防护效
果。研究结果可为轻型水下生产防护系统设计提供有益参考。 |

| In recent years, significant advances have been made in offshore oil and gas extraction technologies, with subsea production systems becoming a key component in the development of deepwater oil and gas resources. However, as offshore resource exploitation intensifies, subsea systems are increasingly exposed to the risk of impact damage from vessels. Therefore, the scientific design of protective structures for subsea production systems is of great engineering and practical significance for effectively mitigating economic losses and preventing marine environmental pollution. This study employs numerical simulation methods to investigate the impact responses of three
types of composite protective structures subjected to dropped objects, anchor impacts, and trawl board collisions. The performance of the
composite protective structures is optimized with respect to two key design parameters: laminate thickness and sidewall inclination angle.
The influence laws of these parameters on the mechanical behavior of composite laminates are analyzed, and the most effective parameter
configuration is identified. The results show that: As the impact velocity increases, the time required for the impacted surface to reach its
maximum indentation depth decreases, while the peak indentation depth increases; With increasing thickness of the protective structures,
the time to reach peak impact response becomes shorter, and the maximum indentation depth reduces accordingly for all three configurations; The protective effectiveness of different designs is sensitive to the inclination angle of the sidewalls, which can be adjusted to enhance overall impact resistance.These findings provide a valuable reference for the design of lightweight protective systems for subsea production facilities. |
