电枢是同步感应电磁线圈炮中的一个关键部件,电枢的结构是影响同步感应电磁线圈炮发射效率的重要因素。建立了同步感应线圈炮电枢磁-结构耦合的数学模型,以电枢总体积为目标函数,建立了基于设计变量、约束条件和收敛准则的圆筒型电枢结构优化数学模型。利用Ansys基于APDL的有限元优化技术进行优化求解,得到了电枢的最佳设计变量,仿真结果表明该设计变量既能满足电枢的几何约束条件和性能约束条件,又使电枢体积较初值减小了78.89%,有效地降低了电枢在弹丸中的配重。
The armature is a key component in the synchronous induction electromagnetic coil gun. The structure of the armature is an important factor that affects the launching efficiency of the synchronous induction electromagnetic gun. The mathematic model of armature magnetostructure coupling is established. Based on the total armature volume as the objective function, an optimized mathematical model of cylindrical armature structure based on design variables, constraints and convergence criteria is established. The optimum design variables of the armature are obtained by Ansys APDL-based finite element optimization technology. The simulation results show that the design variables can meet both the geometric constraints and the performance constraints of the armature, The value is reduced by 78.89%, effectively reducing the armature weight in the projectile.
