摘　　要：使用一个端部配重的单侧翼 ,以提供强非对称的气动力矩而导旋的单翼末敏弹系统 ,越来越受到各国末敏弹研制者的重视 .在这种系统中 ,单翼的柔性变形是客观存在的 .在小变形的假设下 ,分析了系统的受力情况 ,建立了系统的 7自由度模型 .程序算例表明 ,这种柔性结构可以实现稳态扫描 。The researchers in the world pay more and more attentions to the terminal sensing ammunition (TSA) system which utilizes a tip-weighted single-fin to supply strong asymmetric aerodynamic moment to induce spinning. In this system, the single fin is sure to be flexible. On the basis of small deformation assumption, this paper analyzed the system's mechanical situation, and established the 7 degrees of freedom kinetic model. An example indicates that this kind of flexible structure can realize stable scanning. So the model can be used in the studying of TSP total design and scanning equipment design.
