浅析海工设施悬挑型直升机平台支承端的铰接优化

摘要

针对海工设施中广泛使用的悬挑型直升机平台的受力特点，分析了高位铰接优化对避免布置空间不足和缓解局部应力、杆弯曲应力的效果，并基于实践中接触的某直升机平台，使用有限元分析方法进行了对比性核算，验证了铰接优化的可行性。%Aiming at the stress characteristics of the cantilever-type helideck widely used on offshore units, the effects of the hinge-connection in relatively high position on avoiding space-lacking and relieving local stress and bar bending stress are analyzed. Based on one helideck in practice, the contrastive verification by FEA is carried out and the feasibility of the hinge-connection is proved.
