大型振动筛体积、重量大 ,运输安装困难 ,一般必须在制造或使用现场进行性能试验和检测。为缩短现场试验及检测时间 ,在现场采集实验数据 ,实验室里进行数据分析处理的脱机方式得到广泛应用。1检测、记录和分析处理系统检测、记录和分析处理系统框图如图1所示。2现场数据采集2. Large shaker size, weight, transportation and installation difficulties, generally must be in the manufacture or use of site performance testing and testing. In order to shorten the field test and testing time, the experimental data was collected in the field and the offline method of data analysis and processing in the laboratory was widely used. 1 detection, recording and analysis of system detection, recording and analysis of the system block diagram shown in Figure 1. 2 site data collection 2.
