摘要
盾构法是地下交通施工的一项关键技术,在隧道施工建设上得到广泛应用.基于LabVIEW平台,设计盾构机缩比主轴承试验台测控系统.该系统既能够实现对试验轴承施加轴向和径向载荷,以及对试验轴承的振动数据和温度数据的实时采集、显示、处理、记录及保存,又能够将采集到的振动数据对试验轴承进行包含峰值、脉冲、裕度、波形和峭度等指标在内的时域分析和包含频谱、包络谱和倒频谱在内的频域分析.实验结果表明该系统设计合理、运行可靠、结果分析准确,能够满足试验需求,具有一定的工程应用价值.
A test and control system based on LabVIEW is designed.The system can apply axial and radial loads to test bearings,and collect,display,process,record and save the vibration data and temperature data of test bearings in real time.The collected vibration data can be used for time domain analysis including peak value,pulse,margin,waveform and kurtosis,and frequency domain analysis including spectrum,envelope spectrum and cepstrum.Finally,the system is verified by experiments on the test bench.The results show that the system is reasonable in design,reliable in operation and accurate in analysis.It can meet the test requirements and has certain engineering application value.
