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机翼顶升载荷的垂直分量由加强肋承担,主要传递到后梁,水平分量通过挤压由下壁板和加强肋承担。B737机翼顶升接头的连接方式操作简单,但A320机翼顶升接头传力路径更清晰。
韆斤頂頂升情況是民用飛機在進行維脩、更換零部件時必鬚攷慮的一箇狀態。對民機頂升的相關適航條款進行瞭理解;對B737及A320的機翼頂升裝置進行瞭總結對比,通過傳力分析,比較瞭其優缺點。兩種機型的傳力方式稍有不同:B737機翼頂升載荷的垂直分量由加彊肋承擔主要傳遞到前樑,水平分量通過擠壓由下壁闆承擔;A320機翼頂升載荷的垂直分量由加彊肋承擔,主要傳遞到後樑,水平分量通過擠壓由下壁闆和加彊肋承擔。B737機翼頂升接頭的連接方式操作簡單,但A320機翼頂升接頭傳力路徑更清晰。

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.
