摘要
针对无替换定时截尾的数控系统可靠性测试的故障分析的需要,对数控系统可靠性测试的试验运行数据进行了理论分析与研究,通过将离散的测试信号连续化、去噪、提取特征等信号处理技术实现了对大量试验数据的周期识别,为进一步分析数控系统的运行故障情况奠定了基础。
According to the needs of failure analysis of the no substitution and censored CNC system reliability test,study and analyze the running data from CNC system reliability test,by continuous discrete signal,denoising,feature extraction and other signal processing technology to achieve the cycle of a large number of the testing data,lays the foundation for further analysis of the failure in operation of CNC systems.
