摘　　要：弹体斜侵彻硬介质目标过程将发生弹道偏转,甚至发生跳弹。弹体一旦跳弹,使弹体侵入不到目标内部,从而不能对目标形成有效打击。为保证弹体能够有效侵彻目标,需要对弹体侵彻目标的临界跳弹角度进行预测,给出弹体不发生跳弹的角度范围。为此,对弹体斜侵彻硬介质目标的跳弹进行研究,建立了预测弹体斜侵彻目标的跳弹分析评估方法。运用该方法对弹体分别侵彻抗压强度为30 MPa和60 MPa的钢筋混凝土的临界跳弹角度进行计算,并与实验结果进行了对比。结果表明,该方法能比较准确地分析和评估弹体的跳弹角度。The ballistic trajectory of a projectile may deflect or it ricochets off a target when the projectile penetrates a hard target obliquely. Once the projectile ricochets off a hard target,it cannot perforate into the target,which cannot bring effective damage to the target. In order to ensure that the projectile penetrate the hard target effectively,the critical ricochet angles of projectile impacting the hard target need to be predicted,and the range of angles of that the projectile does not ricochet is given. Consequently,the ricochet of projectile penetrating a hard target obliquely is studied,and then an evaluation method of predicting the critical ricochet of projectile is proposed. The critical ricochet angles of projectiles penetrating the reinforced concretes with compressive strength of 30 MPa and 60 MPa are calculated using the proposed method,respectively,and the calculated results are compared with the experimental results. The results show that the evaluation method can be used to analyze and evaluate the ricochet of projectile precisely.
