在建立装载机传动轴扭矩信号采集分析系统的基础上,对装载机典型工况进行了实机测试,应用nsoft软件对试验数据进行了分段与合并处理、滤波与去异值处理以及数据平稳性检验,采用加权求和方法对等间隔子样以及各子样中的作业循环数据进行了处理,制取了装载机典型循环工况下的传动轴扭矩时间历程。 On the basis of establishing the torque signal acquisition and analysis system of the loader shaft, the real working condition of the loader was tested. The experimental data were segmented and combined using nsoft software, and the filtering and denoising processing and data smoothing The test of the sex, the method of weighted summation, the sample of the equal interval and the cycle data of each sub-sample were processed, and the torque history of the transmission shaft under the typical cyclic loading condition of the loader was obtained.
