摘要：
Aiming at the problem that the parameters such as the height, relative distance and termination impedance of the transmission line show uncertainty in the practice, a calculation method for the uncertainty of crosstalk in multi-conductor transmission line is proposed. Firstly, the multi-conductor transmission line model with uncertain parameters is established. Then, according to the multi-conductor transmission line theory, considering that the model has a safety threshold, the random response surface method based on the most likely failure point is used to calculate the failure probability of the multi-conductor transmission line model. By comparison, the failure probability of the model obtained by this method is basically consistent with the calculation result of Monte Carlo method, but its calculation efficiency is greatly improved, and the statistical moment of model crosstalk can be conveniently obtained, so as to realize efficient and accurate prediction of electromagnetic compatibility performance of transmission lines, such as wire harness or circuit board microstrip line in complex systems, such as automobiles. © 2021, Jilin University Press.
