为探讨无伞末敏弹的质量分布特性对其扫描特性的影响规律，在分析质量分布非对称力学表示方法的基础上，建立了考虑质量分布非对称时的弹丸动力学模型，编制了模型的仿真计算软件。以某型非对称末敏弹的结构参数和气动参数为依据，仅改变质量分布特性参数进行数值积分计算，得到了扫描转速、扫描角与横向、纵向转动惯量比以及与动不平衡角之间的关系，为通过调整质量分布参数来调整扫描参数提供了依据。

To discuss the rule of mass distribution characteristics influencing scanning characteristics of non-parachute terminal-sensitive ammunition (NPTSA ),the mechanical description method of the asymmetric distribution of mass was analyzed,and the dynamic model of projectile was established with the consideration of the asymmetric distribution of mass.The simulation software of model was programmed.According to the structural parameters and pneumatic parameters of some kind of NPTSA,numerical integrating was performed in which only mass distribution characteristical parameters were changeable.The relationships between rolling speed,scanning angle and the ratio of the moment of inertia,together with the relationships between rolling speed,scanning angle and the dynamic imbalance angle,were achieved.The study provides the basis for adjusting its scanning parameters by means of adjusting its mass distribution parameters.
