任意拓扑结构汽车线束的故障检测

Fault Detection for Wring Harness of Arbitrary Topology

建立了具有任意拓扑结构的汽车线束故障模型,提出了分组检测线束故障的方法,并运用矩阵降阶预处理和矩阵异或运算算法实现了对被测线束故障的诊断。试验结果表明,该故障检测方法简单,效率高,成本低,可对汽车线束进行通、断及错位故障的检测。

Fault models of automotive wiring harness are built and the method to detect fault of wiring harnesses by group is presented,matrix reduction and algorithm are applied to diagnose fault of the detected harness.The test results show that the proposed detection method has advantages of high efficiency,low cost and ease of use,that can be used in detection of automotive harness faults like disconnection and dislocation.
