摘要:
为了探究着靶角度对PELE侵彻钢筋混凝土靶扩孔效应的影响规律,建立了PELE侵彻钢筋混凝土靶的仿真模型,并且利用侵彻试验结果对仿真模型的准确性进行验证。在0～75°着靶角度范围内,从壳体变形模式、靶板扩孔直径等角度开展了PELE侵彻钢筋混凝土扩孔效应的影响规律与机理研究。研究结果表明:在0～30°着靶角度内,靶板的扩孔尺寸随着角度增大而增大,最大约为4.4倍弹径,并且PELE对钢筋混凝土靶板的破坏功增多; 随着着靶角度进一步增大,靶板的扩孔尺寸反而减小,PELE对钢筋混凝土靶板的破坏功也随之减少。此研究规律可对侵彻毁伤评估、新型动能武器系统设计提供技术支持和理论依据,并可用于指导钢筋混凝土防御工事设计。
Abstract:
In order to explore the influence of target angle on the pore expansion effect of PELE penetrating reinforced concrete target,a simulation model of PELE penetrating reinforced concrete target was established in this paper. The accuracy of the simulation model was verifier with the penetration test. In the range of 0°～75° target angle,the influence law and mechanism of PELE on the reaming effect of reinforced concrete were studied from the perspectives of shell deformation and reaming diameter of target plate. The results show that the reaming size of the target plate increases with the increase of the target angle from 0° to 30°. The damage work of PELE to the reinforced concrete target plate increases with the increasement of target angle. The maximum reaming size of the target can be 4.4 times of the diameter of PELE. With the further increase of the target angle,the reaming size of the target plate and the damage work of PELE to the reinforced concrete target plate decrease. The research can provide technical support and theoretical basis for penetration damage assessment and new kinetic energy weapon system design,and can be used to guide the design of reinforced concrete fortifications.
