THE DYNAMIC STABILITY ANALYSIS FOR THE BULLET BY THE NONAUTONOMOUS SYSTEMS MODEL

摘要

摘要:本文采用与实际比较相符的非定常非线性系统模型,应用定理和状态转移矩阵范数的估值以及矩阵测度公式,分析弹丸的动态稳定性。该文提出了外弹道学中研究动态稳定性问题的一种新理论和新方法。

Abstract:This paper presents the analysis of the dynamic stability of a bullet by use of the nonautonomous nonlinear model which is closer to reality, and by application of the theorems author published before, the theorem of evalution of the state transition matrix and the formulas of the matrix measure.The paper introduces a new theory and method to investigate the stability in the exterior ballistics.
