Uncertainty Analysis of Crosstalk in Cable Bundles with Stochastic Reduced Order Models

This article proposes an uncertainty analysis method for crosstalk in cable bundles based on the stochastic reduced order modeling (SROM) method. First, a multipoint bundled random cable bundle modeling method is proposed by modifying the random midpoint displacement method and the iterative perturbation method for deterministic calculation of nonuniform cable crosstalk are demonstrated. According to the sensitivity analysis results of crosstalk parameters and the geometric characteristics of the cable bundle, dimensionality reduction is applied to the cable model. Subsequently, SROM is applied to perform uncertainty analysis on crosstalk for randomly sampled cable bundles, and the results are compared with a reference benchmark obtained via Monte Carlo method. Finally, experimental tests on cable crosstalk are conducted, validating the effectiveness of the proposed uncertainty analysis method for random cable bundle crosstalk.
