将弹塑性线性强化介质中的空腔膨胀理论推广到弹箭侵彻器的侵彻研究中,建立了弹丸在细密介质中侵彻的二维理论计算方法,对于土壤等软介质则利用莫尔——库仑准则建立了弹丸在土壤中的计算法;在火箭侵彻器的侵彻研究中,开拓了斜置翼片上的介质阻力计算,从而又建立了火箭侵彻器侵彻弹道的理论模型。最后利用本理论对弹箭侵彻器在岩石和土壤中的侵彻弹道进行了计算,得到了与实验很符合的结果,因而验证了本理论的正确性。
The theory of cavity expansion in elasto-plastic linear enhancement media is extended to the study of penetration of projectile and rocker penetrator. A two-dimensional theoretical calculation method of projectile penetration in fine media is established. For soft media such as soil, - The Coulomb criterion establishes the method of calculating the projectile in the soil. In the study of the penetration of the rocket penetrator, the calculation of the medium resistance on the inclined wing was exploited, and the theoretical model of the projectile penetration projectile was established . Finally, this theory is used to calculate the projectile trajectory of the projectile and rocker in the rock and soil, and the results that are in good agreement with the experiment are obtained. Therefore, the correctness of this theory is verified.
