摘　　要：为开展机舱失压环境效应研究,针对大口径泄压通道,设计一种新型的机械式瞬间泄压装置,并进行相关机构运动学、动力学建模研究.该泄压装置主要由弹簧储能机构、连杆式舱门压紧机构、基于SEA(Series Elastic Actuator)的舱门锁紧/释放机构和基于惯性飞轮的电磁式缓冲机构组成,具有操控简单、可靠性高、可重复使用、试验效率高的特点.最终设计的瞬间泄压机构面向DN750泄压通道,舱门从0°开启到90°用时约280 ms.本研究将为今后研发面向大口径泄压通道的瞬间泄压机构,并应用于大型快速泄压环境效应试验装置建设提供参考.To study the fast-pressure-relief effect,a novel mechanical facility capable of instantaneous depressurizing is designed for large-sized pressure relief openings,and the related kinetic and dynamic modeling studies are carried out.The mechanism consists of a spring-based energy storage mechanism,a connecting rod-type latching mechanism,an SEA-based locking/releasing mechanism,and an inertia wheel-based electromagnetic buffer mechanism.It enjoys several advantages like the easy maneuverability,the repeatable usage,and the high testing efficiency.The finally designed fast-pressure-relief mechanism can enable a 750 mm diameter pressure relief door to shift from 0°to 90°position within 280 ms.This work provides some theoretical basis and technical support for the development of the large-sized pressure relief environmental simulation equipment in the future.
