Abstract

本申请提供一种用于验证驾驶舱门泄压锁解锁时间的试验装置,属于驾驶舱门泄压试验领域,其包括:真空环境模拟组件,其包括真空箱、真空泵、真空阀及真空表,真空箱内设有释放板;试验环境模拟组件,其包括试验箱、释放触发电门、释放门闩、压力传感器、观察窗、泄压板保护块、泄压板限位支架及位移传感器,试验箱与真空箱对接,释放触发电门通过释放门闩与释放板连接;当真空泵将真空箱抽真空到预定压力值时,释放触发电门对释放板进行释放,从而使真空箱与试验箱连通而模拟驾驶舱门的高空使用环境,通过位移传感器测量泄压板是否发生位移,进而判断泄压板发生位移时的时间与释放触发电门的释放时间之差,完成泄压板锁定机构的解锁时间验证。
