Research on Disturbance Moment Spectrum of Tank Gun System under High Maneuvering Conditions

doi:10.3969/j.issn.1000-1093.2015.04.002

Abstract

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
