介绍了 3种静气弹发散方法 (柔度法、模态法、颤振法 ) ,并对这 3种方法的一致性从理论上进行了分析和证明。使用这 3种方法对 5个平板机翼模型的发散速度进行了计算 ,其实际发散速度也从低速风洞试验中获得。通过对比计算结果和各模型风洞试验结果 ,进一步验证了这 3种方法的一致性。另外 ,还提出了在模态法和颤振法中基于发散特征向量的结构模态选取原则。 Three kinds of static air-spring divergence methods (flexibility method, modal method and flutter method) are introduced. The consistency of these three methods is theoretically analyzed and proved. The divergence velocities of five slab-wing models were calculated using these three methods, and the actual divergence speed was also obtained from the low-speed wind tunnel tests. By comparing the calculation results with the wind tunnel test results of each model, the consistency of these three methods is further verified. In addition, the principle of modal selection based on divergent eigenvectors is also proposed in modal and chatter methods.
