| 摘 要： | 从矢量形式的六自由度弹丸运动方程组出发,推导出了在全部力和全部力矩作用下考虑几何非线性及力和力矩非线性时的弹丸运动方程组,并导出了其用于数值计算的柯西标准形式,得到了攻角和进动角的计算表达式.此动力学模型可用于弹丸大攻角飞行时的弹道计算及某些灵巧弹药(如末敏弹)的设计.

Study on the Kinetic Equation of Projectile with Consideration of Geometrical Nonlinearity and Force and Moment Nonlinearity |
| |
| Abstract: | Considering the geometrical nonlinearity and force and moment nonlinearity,this paper deduces the kinetic equation of projectile in condition of all force and all moment from the 6 degree of freedom equation in vector form,and also the equation in Cauchy standard form which can be used in numerical calculation.The expressions of angle of attack and angle of precession are obtained.This kinetic model can be used in ballistic calculation of projectile with large angle of attack and also in the design of some smart munitions(e.g.target sensitivity projectile). |
