基于能量函数的故障诊断方法与实验

摘要

There are many possibilities of faults in motion systems which are related to driver equipments,based on the torque monitor signal supplied by systemic driver,a method based on energy function for fault diagnosis and classification of types was proposed.Troubleshooting principle based on the energy function was given,the key points of the application process were ana-lyzed,and a detailed flowchart of the diagnostic process was provided.After the software simulation using Matlab and diagnosis experiments on X-Y-Z motion platform under numeric control arithmetic,the effectiveness of this method was verified.Mean-while,the selection of different energy functions and their parameters was analyzed in detail,and some guidelines about fault dia-gnosis were given.%针对运动系统可能发生多种与驱动装置相关的故障，基于系统执行器提供的力矩监视信号，提出基于能量函数进行故障诊断与类型分类的方法。给出基于能量函数的故障诊断原理，分析应用过程中的关键点，提供详细的诊断过程流程图。通过基于Matlab的软件仿真以及以数控运动平台为对象的诊断进行实验，实验结果表明了该方法的有效性。对不同能量函数及其参数的选择进行详细的分析，给出进行故障诊断的指导性原则。
