摘　　要：大开角扩散段在风洞回路中有着非常广泛的应用,其在跨超声速风洞中具有重要作用。以风洞大开角扩散段法兰联接为背景,根据压力容器国家标准中有关法兰设计的理论,结合风洞大开角扩散段法兰结构的特点,对该类法兰的载荷进行了分析,给出了载荷及其作用位置的计算公式。The wide angle diffuser is widely used in wind tunnel circuits, it has important functions in transonic and supersonic wind tunnel. Taking the flange connection of wide angle diffuser in wind tunnel as the background, according to the principle of flange designin the national standard of pressure vessels, combining the characteristics of flange of wide angle diffuser in wind tunnel, the paper analyzed the loads of the flange, and presented the formulae of loads as well as their positions.
