航空机载弹药着速对侵彻靶板影响的仿真分析

航空机载侵彻型弹药由于姿态调整及过载冲击的影响，对着靶速度有一定的要求，利用冲击波理论对极限撞击速度进行理论计算。应用ANSYS／LS—DYNA分析技术对航空抛撒侵彻型弹药侵彻混凝土靶板进行分析，获取各着速下侵彻过程的速度、加速度曲线，结合极限撞击速度的理论计算值与模拟值比较分析，得到着速对靶板侵彻效果的影响，为引信抗冲击过载加速度传感器的设计及加速发动机功率的选择提供理论支持。

The Affect Simulation Analysis of Initial Velocity of Aviation Airborne Ammunition to the Penetration Target

The aviation aircraft-borne penetration ammunition as a result of the posture adjustment and the overload impact influence, treats the target speed to have the certain request, carries on the theoretical calculation using the shock wave theory to the ultimate impact velocity, Carries on the analysis using the ANSYS / LS-DYNA analysis technology to the aircraft ammunition penetrating concrete target, gains the velocity and the acceleration curves in different Initial velocities under the penetration process, Compared with theoretical numerical value of ultimate impact velocity and simulation numerical value, Obtains Initial velocity to the target penetration effect influence, Provides the theory support for the high G sensor design and the acceleration engine power choice.
