实际测试某轮式装载机传动系载荷信号,根据同步测试的其他信号特征,对测试的扭矩载荷信号进行了按段分割及同段合并的处理方法,即按照空载运行、铲掘装载、重载运行与卸料四段分段处理,并用轮次检验法对信号进行了平稳性检验,验证了处理后信号的平稳性,且符合装载机的真实工作环境,为载荷谱的编制与传动系的可靠性分析奠定了基础。 According to the characteristics of other signals of synchronous test, the torque load signal under test is divided into segments and combined with the same segment, that is, according to no-load operation, excavation load and heavy Load and unload four sections of segment processing, and test the signal using the roundness test to verify the smoothness of the signal after processing, and in line with the real working environment of the loader for the preparation and transmission of the load spectrum The reliability analysis laid the foundation.
