摘　　要：为研究新能源汽车用电驱动总成早期故障,利用早期故障分析设备对新能源汽车用电驱动总成进行耐久试验的振动监测。理论分析与实际监测的结果表明,早期故障分析设备准确预测了故障部位损坏的趋势。准确诊断出电驱动总成早期故障可以及时终止试验,避免样品及台架的过渡损坏,同时,可以快速定位故障部位,缩短产品开发周期。In order to study the early faults of the electric drive assembly of new energy vehicles,early fault analysis equipment is used to monitor the vibration of the durability test of the electric drive assembly of new energy vehicles.The results of theoretical analysis and actual monitoring indicate that the early fault analysis equipment accurately predicted the trend of damage at the fault location.Accurately diagnose early faults of the electric drive assembly,it can terminate the test timely,avoid transitional damage to the sample and bench,and quickly locate the fault location to shorten the product development cycle.
