基于多色集合的数控机床故障诊断模型构建与推理方法
Modeling and reasoning method of fault diagnosis of CNC machine tools based on polychromatic sets
摘要
Abstract
The faults of CNC machine tools have the complex characteristics of hierarchy and cor-relation.It’s an important process of fault diagnosis of CNC machine tools to establish and rea-son a formal structure model of fault diagnosis.Based on polychromatic sets theory,a formal modeling and reasoning method of fault diagnosis for CNC machine tools was proposed.The basic concepts of polychromatic sets (PS)were introduced and a PS-based hierarchical structure model of fault diagnosis for CNC machine tools was established.On the basis of the element,individual pigmentation and unified pigmentation,the structure model of fault diagnosis for CNC machine tools is described formally from horizontal and vertical direction.The reasoning algorithm of fault diagnosis model for CNC machine tools was proposed,and the top-down of fault diagnosis model was reasoned automatically.Finally,the fault model of tool carrier system is used as an example to illustrate the correctness and feasibility of the proposed theory and method.关键词
