| 摘 要： | 针对平衡炮试验中常用的前后定心式弹托设计，在文献［3］Forrestal侵彻模型基础上，建立带前后定心式弹托的刚性弹体侵彻模型，分析弹托相对附加质量、弹托组件与弹体连接强度、侵彻着速等因素对弹体侵彻终点效应的影响规律。分析结果表明：弹托附加质量越大，对侵彻深度增益越明显；随着侵彻初速的提高，弹托附加质量对侵彻深度增加量的影响逐渐增大，弹托的连接强度对侵彻深度的影响越来越小。

| Abstract: | In order to optimize the design of the forward and back centering sabots which are commonly used in the Davis Gun system, a penetration model of rigid penetrator with sabot is established based on the Forrestal penetration model, and the influences of the relative sabot mass, the connection strength between sabot component and projectile and the impact velocity on projectile penetration are analyzed. The results indicate that the penetration depth increases obviously with the increase in sabot mass. The effect of the sabot mass on the penetration depth augments gradually while the effect of the connection strength on the penetration depth get smaller with the improvement of the impact velocity. |
