基于Mutisim10的电子电路故障诊断

Fault Diagnosis of Electronic Circuit Based on Multisim10

将Mutisim10仿真软件应用于电子电路故障诊断。首先根据实际电路中故障现象及示波器测量输出波形分析可能的故障元件及故障元件可能存在的故障,并设置第一步分析出的故障元件的相应故障。接着仿真设置后的电路,观察示波器的输出波形是否与实际电路的故障现象一致。若一致,检验实际电路的相应元件是否出现相应故障,反之改变设置元件的"fault"属性,直到输出的故障现象与实际电路一致为止。

Use MutisimlO simulation software in the fault diagnoses of electronic circuit. First, analyze the possible fault components and faults depending on graph transformed by the oscilloscope. Then set the same fault in the simulated circuit. Check whether the graph after simulating is consistent to the graph got from the real circuit. If they are, check the corresponding component. If they are not, modify the ＂fault＂ attribute of the simulated circuit till the two graphs are consistent.
