高冰级吊舱推进器系统维修保障分析研究OA
Analysis and Research on Maintenance and Support of the high polar-Ice-Class pod propulsion systems
针对高冰级吊舱推进器在远海冰区维修困难的技术瓶颈,本文开展了以可靠性为中心的维修(RCM)保障研究.通过系统功能与故障分析,识别出推进及转舵轴封为关键子系统,并采用故障模式、影响及危害性分析(FMECA)方法,明确了"密封失效且无法海上更换"为最突出的薄弱环节.据此,提出了创新性的模块化海上可维修设计改进方案.最终,结合分析结论与设计特点,制定了差异化的系统预防性维护策略.本研究提供了从分析、设计到策略制定的全流程解决方案,对提升高冰级吊舱的作业可用性与全生命周期经济性具有实用价值.
Aiming at the technical bottleneck of difficult maintenance for high-Ice-Class pod propulsors in remote ice areas,this paper investigates a Reliability-Centered Maintenance(RCM)support.Through a systematic functional and failure analysis,the propulsion and steering shaft seals are identified as the critical subsystems.Using the Failure Mode Effects and Criticality Analysis(FMECA)method,"seal failure with inability to perform rapid replacement at sea"is pinpointed as the most prominent weakness.Accordingly,an innovative modular at-sea maintainability design solution is proposed.Finally,a differentiated systematic preventive maintenance strategy is formulated by integrating FMECA conclusions with design improvement features.This research provides a full-process solution spanning analysis design and strategy formulation for constructing a maintenance support system of high-Ice-Class pods.,holding practical value for improving the operational availability and lifecycle economics of high ice-class pod propulsion system.
