火箭弹起始扰动的仿真与试验研究

目的 研究火箭弹起始扰动的形成与减小火箭弹起始扰动的技术途径。方法 通过计算机数值仿真和射击试验，对影响火箭弹起始扰动的因素进行分析。结果 得到了发射过程中各种扰动因素对火箭起始扰动影响的量值。结论 推力偏心、动不平衡、弹管间隙、俯仰体振动及车体振动对火箭弹起始扰动的影响较大，应该在火箭武器系统设计中对此加以考虑。

Simulation and Test of Rocket Initial Disturbance

Aim To study the forming and decreasing of rocket ini tial distur-bance. Methods The factors affecting rocket initial disturbance was anal yzed through computer numerical simulation and firing test. Results The relations between the rocket initial disturbance and various affecting factors. Conclusion Thrust eccentricity, unbalance, clearance btween rocke t and launching tube, vibration of pitching body and carrier are main factors af fecting rocket initial disturbance, which should take into account in the design of rocket system.
