摘要/Abstract

摘要： 随着坦克机动速度的提高和路面复杂程度的增加，火炮所受扰动力矩的幅值和频率急剧增大，严重影响了炮控系统的稳定精度和射击命中率。为此，建立火炮系统动力学模型，分析扰动力矩的作用机理、影响因素及其测试方法。在此基础上提出基于希尔伯特-黄变换（HHT）的火炮扰动力矩时频谱分析方法，系统分析主振频带、约束频带和特征幅值等扰动力矩典型频谱特征及其对炮控系统设计的影响。研制了扰动力矩谱测试系统并应用于工程实践，为高速机动条件下火炮扰动谱测试分析和炮控系统设计研制提供理论依据与技术支撑。

Abstract: The amplitude and frequency of disturbance moment putting on gun are quickly increased with the increase in the maneuvering speed of tank and the complexity of road. As a result, the stabilized accuracy and hitting probability are seriously affected. For the problem above, a dynamics model of tank gun system is built, and then the action principle, affecting factors and test method of the disturbance moment are analyzed. On the basis of that, the Hilbert-Huang transform (HHT)-based time-frequency spectrum analysis method of disturbance moment is proposed, the typical spectrum characteristics (including main vibration frequency band, constraint frequency band and characteristic amplitude) and their influence on design of tank gun control system are analyzed thoroughly. Finally, a disturbance moment spectrum test system is designed and applied in engineering practices, establishing both the theoretical evidence and technical support for disturbance moment spectrum analysis and design of tank gun control system under high maneuvering conditions.

Key words: ordnance science and technology, tank gun system, disturbance moment, time-frequency spectrum, Hilbert-Huang transform
