The invention provides an analysis method of a cam handle type quick-release expansion device, which comprises the following steps: determining the relationship between the axial force of a taper sleeve and the locking force based on a friction coefficient, a first preset distance and a second preset distance; determining the axial force of the taper sleeve based on the relation between the axial force of the taper sleeve and the locking force; determining an axial compression amount based on the axial force of the taper sleeve; based on the conical surface number, the conical surface angle and the axial compression amount, the radial expansion amount of the conical sleeve is determined; the hydraulic rod is arranged to provide assistance for opening and closing of the fairing, and buffering is provided at the moment when the fairing is completely opened; after the fairing is opened, the pedal can be automatically lifted through the linkage pull rod for maintenance personnel to tread; when the fairing is closed, the pedal automatically retracts, and the flight resistance of the helicopter is reduced; when the fairing is opened, the pull rod occupies a small space and is convenient to maintain.
本申请提供的一种凸轮手柄式快卸膨胀装置的分析方法,所述方法包括:基于摩擦系数、第一预设距离和第二预设距离,确定锥套轴向力与上锁力之间的关系;基于所述锥套轴向力与上锁力之间的关系,确定锥套轴向力;基于所述锥套轴向力,确定轴向压缩量;基于锥面对数、锥面角度和所述轴向压缩量,确定锥套径向膨胀量;本申请设置有液压杆为整流罩打开和关闭提供助力,并且在整流罩完全打开的瞬间提供缓冲;整流罩打开后通过联动拉杆能够自动升起踏板,供维护人员踩踏;整流罩关闭时踏板自行收起,降低直升机飞行阻力;整流罩打开状态,拉杆占用空间小,便于维护。
