摘　　要：为研究无伞双翼末敏弹的运动规律,针对无伞双翼末敏弹弹体结构不对称、质量分布不对称的特点,建立了相应的坐标系,给出了相应的坐标转换矩阵,分析了作用在其上的所有力和力矩,推导出了各力和力矩的表达式.以某组气动参数和结构参数为例,采用所建的力和力矩模型进行弹道计算,可以形成稳态扫描运动.表明所建模型是正确的,可用于指导该类末敏弹的总体设计.To study the kinetic rule of double-win terminal sensing ammunition（TSA） without parachute, aiming at its asymmetric structure and mass distribution, corresponding reference frames and coordinates transformation matrices were set up. All forces and moments acting on the TSA were analyzed, and their expression formula were deduced. Taking certain group pneu- matic and structural parameter as an example, trajectory calculation was carried out by the force and moment model proposed in this paper. The result shows that this kind of TSA can generate stable scanning motion, and the forces and moments models are right, and the result can be used to guide total design of TSA.
