摘　　要：为了研究弹体侵彻混凝土后的质量损失,提出满足工程需求的计算方法,以侵彻混凝土靶后的弹体为研究对象,分析了影响弹体质量损失的相关参数。利用量纲分析的方法建立了弹体侵彻混凝土的相似模型和相似准则,回归了工程计算公式。研究结果表明,该公式具有良好的计算精度和较宽的适用范围。In order to study the mass loss of projectile penetrating concrete target and work out the design formula that can meet engineering requirement,the relative parameters that influence projectile mass loss were analyzed.Through dimensional analysis,the reduced-scale model and similar criteria for high-velocity projectile penetrating concrete target were established for regressing concrete engineering computing formula.The test results indicate that the formula is of higher adaptability and accuracy.
