本文主要探讨处理炮身振动特征值及特在向量问题。文中以小口径高炮炮身为研究对象,建立了相应的力学模型,并采用SAP5程序解出其固有振动特性。之后,着重论述了影响炮身固有振动特性的诸因素,并提出了改进的技术措施。 This paper mainly deals with the problem of dealing with the eigenvalue and special vector of the vibration of the gun's shell. In this paper, the small caliber artillery gun body as the research object, the corresponding mechanical model was established, and the inherent vibration characteristics of SAP5 program were solved. Afterwards, the factors that affect the inherent vibration characteristics of the barrel are emphatically discussed, and the improved technical measures are put forward.
