机翼结构设计是飞机结构设计最核心内容之一，机翼下壁板设计是机翼中的关键内容之一，其设计水平直接影响整个飞机研制的周期、费用和可靠性，甚至关系到飞机使用寿命。在飞机初步设计阶段，亟需快速有效的机翼下壁板设计方法作为指导，以便实现快速迭代，缩短研制周期，减少研制费用。基于以上需求，对机翼下壁板初步设计方法进行探讨。%Wing structure design is one of the most important parts of aircraft structure design. The lower wing panel is one of the key parts in wing design. The design level of the aircraft has a direct influence on the development cycle, cost and reliability of the aircraft, even directly related to the aircraft life. In the aircraft preliminary design phase, the rapid and efficient design guidance method for the lower wing panel is urgent needed, in order to achieve rapid iteration, shorten development cycle, and reduce development cost. Based on the above requirements, the preliminary design method for lower wing panel is discussed.
