摘　　要：设计一套新型的增压预防机构,实现了监测舱门闩锁机构、增压预防、快速泄压、机构破损安全、2 psi锁定、破冰多项功能。利用Adams软件对增压预防机构进行动力学仿真,满足动力学要求。在动力学仿真的基础上对增压预防机构做了静强度分析,结果满足设计要求。研究成果表明该新型增压预防机构设计方案可行,既减轻了机构的重量,又增加了机构的安全性。所给出的完整的民用飞机舱门增压预防机构设计流程,为今后民用飞机舱门增压预防机构设计提供了必要的技术依据。Designing a new type of vent flap mechanism could achieve monitor door latch and lock mechanism,prevention of pressure,quick release pressure function,fail-safe,2 psi locking,icing and many other functions.Adams software is used to simulate the dynamic simulation of the vent flap mechanism to meet the requirement of dynamic. On the basis of the dynamic simulation,the static strength analysis is done for the vent flap mechanism,and the result meets the design requirements. Research results show that the new type of vent flap mechanism design is feasible. It not only reduces the weight of the mechanism,but also increases the safety of the mechanism,and the complete design flow of the vent flap mechanism of civil aircraft pressurized door was given. The research can provide the necessary technical base for the future vent flap mechanism of civil aircraft pressurized door.
