摘要: 以机械工程中液压系统为研究对象,在理论分析和大量实验研究的基础上,发展了一种基于电阻应变计的液压系统应变监测技术。通过对监测信号的提取和分析,提出了在设计液压系统管路时,应尽量减少弯管数量或增大弯曲半径,给出了如何选取信号检测桥路和应变监测信号。应用分析表明:应变监测技术适合于工业现场液压系统的在线监测与分析。Abstract: A strain monitoring technique for hydraulic system based on resistance strain gauge is developed though theoretical and experimental studies.By analyzing the extracted monitoring signals,it is concluded that in the design of hydraulic piping system,the number of bend should be minimized or the radius should be increased.And the principle of how to select the detection bridge and the strain monitoring signals is also presented.The application example shows that the strain monitoring technique is suitable to the online monitoring and analysis for hydraulic systems.
