摘要
探讨了知识库系统技术在工艺知识系统化处理方面的应用,介绍了一个基于规则表示的工艺知识库及其管理系统;在此基础上,应用面向对象技术及数据库技术,提出了面向对象的工艺知识表示及基于数据库管理系统的工艺知识库系统结构,并认为以工艺知识库管理系统的开发来促进CAPP应用系统的开发。
In this paper,the transter matrixes of lateral/tortional couplig associiated with axial force and the coupling matrix of axial bending torsion are provided.On the basis of reference book,a common program for calculating tateral/tortional coupling critical speed and that of lateral/tortional coupling unbalence response of mutiple rotor system are set up by using equivalent stiffness and damping. The effects of torsional vibration, deformity structure ,oil film stiffness & damping on critical speed are analysed . Finally,calculation and analysis are carried out with one type of engine′s rotor.
