民机机翼千斤顶顶升装置分析

千斤顶顶升情况是民用飞机在进行维修、更换零部件时必须考虑的一个状态。对民机顶升的相关适航条款进行了理解；对B737及A320的机翼顶升装置进行了总结对比，通过传力分析，比较了其优缺点。两种机型的传力方式稍有不同：B737机翼顶升载荷的垂直分量由加强肋承担主要传递到前梁，水平分量通过挤压由下壁板承担；A320机翼顶升载荷...

Analysis on the Wing Jacking Equipment of Civil Aircraft

Jacking condition must be considered when maintaining and replacing parts of a civil aircraft. In this paper, relevant airworthiness standards is be analyzed, and the advantages and disadvantages of the 13737 and A320 aircraft wing lifting devices is compared, through the force transmission analysis. Vertical component of the 13737 wing jacking load is home by the reinforcing rib and pass to the front spar, horizontal component is borne by the lower skin through the hearing. Vertical component of the A320 wing jacking load is home by the reinforcing rib and pass to the rear spar, horizontal component is borne by the lower skin and the reinforcing rib through the bearing. The aircraft wing jacking connection joints of 13737 is simple, but the force transmission of A320 aircraft wing lifting connection is clearer.
