At the same time, the self—exciting force with indicial function formulae put forward by R. H. Scanlan is extended to the three— dimension analysis and separated into the quasi—steady part and the part related to the past history of the structure. The former is interpreted by the aerodynamic damping and aerodynamic stiffness, the later, by the load. Then, the self—exciting force related to the structure motions can be easily introduced.

然后，将Scanlan提出的自激力的阶跃函数表达方法推广运用于三维分析，并将自激力分为似定常部分和与过去响应历程有关的部分，进而分别用气动阻尼、气动刚度和外荷载的形式来描述，从而实现了引入与结构运动相关的自激力。
