摘　　要：编制工程机械载荷谱需要大量实际工况下的载荷时间历程数据,为此,研究实时测试挖掘机载荷的方法。针对不同载荷,选用区别化的测试方案,设计易连接、可重复利用的信号采集系统。试验结果证明了此测试方法的可行性和准确性,为挖掘机载荷谱的编制奠定了实测数据基础。此测试方法具有广泛的通用性,可应用于农机、汽车以及船舶等多个领域。A study on how to test load data at the hydraulic excavator. In view of requirements for massive data on loading duration under actual working conditions as needed in compiling a load spectrum for the construction machinery we carried out a study on an excavator's load test at real time. When pin-pointing various types of load we adopted alternatives of individual testing and designed a signal gathering system of easy connection, and repeatable usage. Test results and analyses show feasibility and accuracy of our test method, thus providing an actual-test basic data for compiling excavators' load spectrum, and that this test method of ours has got a wide-spreading utility as applicable to fields including farm machinery, automobiles, marine, etc.
