摘要: 介绍了作者关于动能深侵彻弹研究的部分工作。单纯动能弹侵彻存在侵彻深度上限，在技战术指标一定的前提条件下，弹体结构的优化可令动能深侵彻弹尽可能实现最大侵深。其中弹体结构的力学设计尤为重要，如弹形、弹材、质量比、长径比等。进一步开展弹体结构设计的力学研究，包括头部设计、战斗部后盖、装填比、弹形和弹材、侵彻效应中的尺度律、混凝土靶的设计，最后给出若干实例。

Abstract: The mechanics problem in structural design of earth penetrating weapons (EPW) has been presented in this paper. There exists a maximum penetration depth for a pure KE projectile when its geometric configuration and impact conditions are specified. However, the structural optimization of EPW, especially the mechanical design of projectile body, is quite beneficial to improve the penetration capability. Analyses are conducted on designs of projectile nose, warhead rear cover, backfill ratio, projectile shape, materials, and the scaling law as well as the design of concrete target. Some examples are given to demonstrate the theoretical results.
