| 摘 要： | 该文讨论了形状类似的射弹侵彻相同混凝土厚靶问题，假定已知经验公式在不完全相似条件下仍成立，研究了原型和模型实验的侵深比、弹长比、弹径比和弹体质量比之间的关系．在不完全相似模型实验中，模型射弹质量较小时WES公式计算的侵彻深度小于Hughes公式的结果，质量较大时结论相反．

| Abstract: | This paper discusses the effects of an impact on concrete barriers caused by similarly shaped but not necessarily proportional projectiles. Under the assumption that the known empirical formulae still stand for non-perfect similar conditions, the expressions for penetration depth ratio, length ratio, diameter ratio and mass ratio between the simulator and the simulated projectiles are developed. When the mass of the simulator is less (or more) than the one of the simulated projectile, the penetration depth of WES formula is less (or more) than the one of Hughes formula under non-perfect similar condition. |
