试验设计在实验设备可靠性分析中的应用

为了掌握实验设备的运行质量状况,从质量管理的角度出发,提出把实验设备纳入测量系统范畴的试验设计(DOE)方法。根据DOE的原理,在测量系统中用统计方法设计试验,采集、分析响应数据,确定测量系统的显著影响因素,从而对实验设备进行可靠性分析。采用DOE分析传感器测量系统可靠性的实例表明,DOE能够以相对少的实验运行次数,最大化掌握测量系统的有用信息,找出测量系统可靠运行的最佳状态,是高校实验设备可靠性分析的一种实用方法。

Application of DOE in Reliability Analysis of Experimental Devices

The reliability of experimental devices directly impacts the quality of experimental teaching in colleges and universities.In order to understand the status of the operation of experimental devices,a novel method is presented from the perspective of quality management by bringing the experimental teaching devices into the category of Measurement System Analysis and analyzing them with the DOE.According to the principle of the DOE,by using the statistical tool,the experiments are designed in the measurement system,the testing data is collected and analyzed,the significant factors are identified by confirmation operations,and the reliability of experimental devices is analyzed.The application of the DOE in the reliability analysis of sensor measurement system shows that DOE is a practical method in laboratories of colleges and universities with the advantages of getting the maximum useful knowledge with a relatively few number of experimental operations to find out the best operation condition.
