近年来,在飞机制造业中明显地出现了采用大型整体模锻的飞机零件(发动机架、机身隔框、机翼整体壁板)之趋势。所设计的整体模锻件的突出特点是:外廓尺寸大,腹板薄、筋高。同时,要求设计人员采用小的模锻斜度和连接半径也是相当重要的,因为模锻斜度和连接半径是与飞机结构中整体模锻件的有利重量的使用可能性相矛盾的。本文的目的在于确定筋高与腹板厚度的实际可能之比值,以及在现代功率的压
In recent years there has been a clear trend in the aircraft industry in the use of large integral forged aircraft parts (engine racks, fuselage bulkheads, wing integral siding). The design of the overall forging pieces of salient features are: large size, thin web, tendons high. At the same time, it is also important that designers be required to employ small swage and connection radii because the draft and connection radii are in conflict with the possibilities of use of the overall weight of the integral die forgings in the aircraft structure. The purpose of this paper is to determine the actual ratio of web height to web thickness,
