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。
Jack jacking situation is civilian aircraft in the maintenance, replacement parts must be considered a state. The related airworthiness clauses of civil aircraft jacking are understood. The wing jacking devices of B737 and A320 are compared and compared, and their advantages and disadvantages are compared by force analysis. The force transmission modes of the two models are slightly different: the vertical component of the wing lifting load of B737 is mainly transferred to the front beam by the reinforcing rib, and the horizontal component is borne by the lower wall panel by pressing. The vertical load of the A320 wing lifting load The component is borne by the stiffener and is mainly transmitted to the back beam, the horizontal component being pressed by the lower wall and the stiffener. The connection to the B737 wing jack is easy to operate, but the A320 wing jack is more force-loaded.
